Create a Lab Environment for Network Automation

0:10Hey guys, and welcome to the very first skill

0:12in the Advanced Network Automation with Cisco

0:15and Python course.

0:16I must say, I'm really quite excited about what

0:18we're going to learn together.

0:20And I really do hope you enjoy the ride.

0:22So let's discuss what we're going

0:24to be doing within this skill, and that

0:26is building our very own network automation environment.

0:29Now, what exactly is a network automation environment?

0:33OK, so let's talk about it.

0:35Now, what I will say is that if you're already

0:37confident about how to build a network automation environment,

0:41then feel free to skip this introductory skill

0:43and go straight to learning about the tools

0:45we're going to be using within this course.

0:47But even if you do know how to build a network automation

0:50environment, I'm still going to recommend that you stick around

0:52and watch this skill, because I really

0:54do believe it's going to be helpful for you.

0:56So let's talk about what we're going to be

0:58covering within this skill.

1:00Now, the very first thing which we're going to have to do

1:02is install VMware.

1:04This is going to host our virtual machines where we're

1:07going to be installing our automation system as well

1:11as the software to be able to simulate our network

1:13topologies.

1:14So we'll walk through the downloading and installation

1:16of VMware as well as how to configure the correct network

1:20in between virtual machines.

1:21Next, we're going to talk about how you can install

1:23a software called EVE-NG.

1:26Now, if you're unaware of what EVE-NG is,

1:28it is software, which is going to allow us to build

1:32our network topologies.

1:33So that is going to be very crucial for us.

1:35Next, we'll discuss how we can download and install

1:38into our EVE-NG machine our Cisco images.

1:42Now, the caveat with installing Cisco images

1:45is that you do actually have to pay for a license

1:48to be able to get these images.

1:49And we'll go through what type of license that

1:51is when we get to that Nugget.

1:53However, I'm fully aware that not everyone

1:55can afford to just go and splash money

1:57on buying a Cisco license.

1:59So I also want to provide an alternative

2:01and that is downloading the free Arista images.

2:05Now, if you're unsure what Arista is,

2:07Arista is basically another vendor, much like Cisco,

2:10just like you have Juniper or Nokia.

2:13But the good thing about the Arista images

2:15is that they're free to download,

2:17and the command line is almost identical to the Cisco command

2:21line.

2:21So all your show IP interface briefs, all your show runs,

2:25all your configure terminal commands,

2:26they're all going to be the exact same using these Arista

2:29images as you would get on the Cisco images,

2:32the difference being is that you don't have

2:33to pay for the Arista images.

2:35So we'll walk through how we can download and install the Arista

2:38images into EVE-NG also.

2:40What we're also going to cover is the installation

2:43of an Ubuntu virtual machine.

2:46Now, this virtual machine is going

2:47to act like our development environment.

2:50This is where we're going to install all of our automation

2:52tools such as Python and Python-based automation

2:56frameworks such as the Nornir framework, which

2:59we'll definitely see a lot of in this course.

3:02Now, to be able to write our code within an Ubuntu VM, what

3:05I'm going to go through is the installation

3:07of something called VS code, Virtual Studio code.

3:11This is a really exceptional cross-platform IDE,

3:15which is an integrated development environment,

3:17and it is perfect for writing codes and managing

3:20configuration text files.

3:21Now, I'm going to go through two different ways we can install

3:24VS code, that is, locally on our Windows machine,

3:27and be able to do something called Remote

3:29SSH into our Ubuntu server, or if you prefer,

3:34I'm also going to walk through how

3:36you can install VS code directly within this Ubuntu VM.

3:40Now, what we'll also cover is the very important concept

3:43of OOB.

3:45This is out-of-band management.

3:47This is going to provide us an easy way

3:50to automate our network without relying

3:52on the connectivity of our production network.

3:55This is a very, very important topic.

3:57Now, if you don't want to have to rely on things like EVE-NG

4:01and installing images, what I also want to introduce to

4:04you is how you can use the Cisco DevNet Sandboxes.

4:07Now, these Cisco DevNet Sandboxes

4:10are really, really great.

4:11And whilst they do have some limitations, which we'll

4:13talk about, they really are a great resource

4:16as a way to test your automation solutions.

4:19And the best part yet is that they're super,

4:21super easy to access.

4:22So these are some of the topics that we're

4:24going to be covering within this skill,

4:26and I really do think it's going to be valuable

4:28for you to follow along with the process

4:31as demonstrated before we dive into the fun stuff of how

4:34to actually automate these networks.

4:36OK, so enough of the talking.

4:37Let's get to action.

4:38What we're going to be doing first is installing VMware,

4:41and that is coming up in the very next Nugget.

4:43So I hope this has been informative for you,

4:45and I'd like to thank you for viewing.

0:10Hey, guys.

0:10And welcome back.

0:12So in the previous Nugget, we just laid out the rough plans

0:14that we have for the skill.

0:16And the very first thing that we decided that we want to do

0:19is to be able to install VMware.

0:21This is where it all starts.

0:23This is a crucial component to be

0:24able to getting your automation environment up and running.

0:27So let's get to it.

0:28So what I want you to do is to open up your browser of choice.

0:31I'm going to use Firefox here.

0:33And what I'm going to search for is VM Workstation Player.

0:36So we hit Enter, and we have this link at the very top here.

0:39Download VM Workstation Player, VMware.

0:42Let's go to this case.

0:43I'm just going to scroll down a little bit here.

0:45OK.

0:46So what I will say up front is that I have a Windows machine.

0:49I don't have access to any Mac.

0:50So unfortunately, I can't walk through the Mac installation

0:53for you.

0:54As best I understand, if you want to use VMware on a Mac,

0:57I think you have to use VMware Fusion.

0:59So if you're using a Mac, then be sure to check that out.

1:03So what I'm going to click here is try workstation 16.0 player

1:07for Windows, and I'm going to click Download Now.

1:09So let's do that then.

1:10Now, straight away we have this pop-up here.

1:13All I'm going to do is select Save File.

1:16So let's click Save File.

1:17And if you go to Download, that should be downloaded.

1:20So what I'm going to do is go to my Downloads

1:22and then click this link here.

1:24So what it's going to do is take me to the Setup Wizard.

1:26So what I'm going to say here is Next.

1:28And I'm going to accept the license agreement and Click

1:31Next again.

1:31Now, it's going to give you the option of where

1:33you want to install to.

1:35Now, it's going to automatically try to install in the C drive

1:38here.

1:39Now, my C drive is running a little bit low on space.

1:42So what I'm going to do is change it to my D drive,

1:44where I have plenty of space.

1:45If you want to use your C drive, then by all

1:47means leave it as is.

1:48So I'm going to click Change here.

1:50If I click on this part here, go to D drive,

1:53now I've created a folder here called New VMware Install.

1:57This is where I'm going to choose to install VMware.

2:00So I'll click this and say OK.

2:01But you can choose whatever you please.

2:03So what I'm going to say is add VMware Workstation Console

2:06Tools.

2:06Enter the system path.

2:07Say Next, and what I'm going to do is uncheck these boxes.

2:10I'm really not interested in this for now.

2:12And I'll Click Next.

2:13And I want to have the Desktop and the Start Menu shortcuts

2:16created so I'll say Next and just click Install.

2:19And now the installation is going to begin.

2:21This shouldn't take too long, maybe a few minutes at most.

2:23Perfect.

2:24So what it's saying here is that the installation has completed.

2:26I'm just going to click Finish.

2:28So I know have this icon here on my Desktop.

2:30Let me click this, and now I have VM Workstation 16.0 Player

2:34installed and ready to go.

2:36So now that we have VMware installed, what we now

2:38want to do is to install EVE-NG within VMware.

2:43Now, how do we do that?

2:44Well, that's what we're going to be covering

2:45in the very next Nugget.

2:46So I hope this has been informative for you,

2:48and I'd like to thank you for viewing.

0:00[MUSIC PLAYING]

0:09Hey, guys and welcome back.

0:11So in the previous Nugget, we had just

0:13installed a VM Workstation Player,

0:15and we had decided that we want to be able to install EVE-NG

0:18so that we can begin building network

0:21topologies for automation.

0:23So let's get to it.

0:24Now, the very first thing which I want to do, again,

0:26is to open my browser here.

0:28I'm going to choose Firefox.

0:29And all I'm going to do is search for EVE-NG.

0:32So If I go to the website here, and at the very top,

0:35I click Download.

0:36Then what I will say is that with EVE-NG,

0:38you do have the option to be able to install

0:40a professional edition.

0:41Now, this requires a license which you have to pay for.

0:45You do get additional features.

0:46But they're not absolutely mandatory for what

0:48we need to be able to do.

0:49So what we are going to be doing is installing the Free EVE

0:53Community Edition.

0:54So what I want to do is just scroll down a little bit here,

0:56just move down.

0:57And now we're at the section where we have the Free

1:00Community Edition.

1:01Now, you do have the option to install the ISO or the OVF.

1:05Now, the easiest way, in my opinion, is to install the OVF.

1:09So we're going to be clicking one of these links here.

1:11Now, what I'm going to choose is the MEGA mirror.

1:14So let's go and click on that just now.

1:16That should open up this link here.

1:17I'm going to accept the cookies, and all I'm going to do

1:20is click Download.

1:21And this is about a 1 gigabyte download.

1:23So it may take a little bit of time,

1:24depending on your internet connection.

1:27So what I'm going to say here is click Save File.

1:30And if I go up to my Downloads, and I right

1:32click this and open Containing folder.

1:34So what I want to do here is right

1:36click this and click Extract All.

1:38Now, what I'm going to do is click Extract again,

1:41and this is going to go through the extraction process.

1:43Perfect.

1:44So what I can now do is double click this folder.

1:46And now we can see here, we have this OVF file here.

1:50And this is what we want to be able to install

1:52into our VMware.

1:54So let's go back to VMware and import this then.

1:57OK.

1:57So I go back to VMware.

1:58I'm going to say Open a Virtual Machine.

2:01And all I'm going to do is browse to that same location.

2:04So in my case, it was in Firefox Downloads, EVE-NG COMM.

2:07And then we have this OVF file here.

2:10So click on this and choose Open.

2:12Now, what I need do it is to give my VM a name.

2:15So I'll just say EVE-COMMUNITY-VM,

2:17and then I'm going to choose the storage path.

2:19But I want to store this VM, again, like I said,

2:22my C drive is running little bit low.

2:24So I'm going to change the location to the D Drive.

2:26So I'll click Browse.

2:28I'll go into my D Drive, and I created this folder called

2:31EVE-NG-INSTALL-LOCATION.

2:32So I'll click OK and then choose Import.

2:35So we know how this VM called EVE-COMMUNITY-VM.

2:38What I want to do is select Edit Virtual Machine Settings.

2:41Now, realistically, how much memory

2:43do you want to give this VM?

2:45Well, as much memory as your computer can actually afford.

2:48If you've got a lot of memory available,

2:50then certainly give the VM as much memory as you can.

2:53This is only going to help performance when

2:54you build large topologies.

2:56In my case, I've got a 16 gigabyte laptop.

2:59I'm just going to give it 8 gig, and I'll leave the processors

3:01at 4 at the moment.

3:03Then what I'm going to do is change the network adapter.

3:06I'm going to change it to NAT.

3:07This is going to share the host IP address.

3:10So I'll click OK.

3:11And that is ultimately the only real change I'm going to make.

3:14So with those VMs selected, I'm going

3:15to choose Play Virtual Machine, click this,

3:18and this is going to turn the virtual machine on.

3:20Now it's given me this option that there are VMware

3:22tools for Linux available.

3:23Do I want to install them?

3:25I'm going to click Download and Install.

3:27And they are going to install for me.

3:29Now, the username is going to be root in lowercase,

3:32and the password is going to be the word eve in lowercase.

3:36So let's take that and then-- so I'll say, root

3:38and then I'll say, eve.

3:39Hit Enter.

3:40So I'll take eve for the root password.

3:42And then I'll repeat the same password, eve again.

3:45Now what do I want to call the host name for the system?

3:47I'm just going to leave it as EVE-NG.

3:50So just push Enter.

3:51I'm not going to be using a DNS domain name,

3:53so I'm just going to click Enter with example.com.

3:56Now, do I want to use DHCP or a static IP address

3:59for the network adapter?

4:01I'm going to leave it at DHCP and just click Enter.

4:04Do I have an NTP configured?

4:06I do not.

4:07So again, I'm just going to leave

4:08this blank and click Enter.

4:09Now, how do I want the VN to be able to connect

4:11to the internet?

4:12I'm just going to leave it at direct connection.

4:14So I'm just going to again hit Enter.

4:16And that's all we need to do.

4:18Super, super simple.

4:19So what I want you to notice here

4:20is is that it actually does tell me the IP address,

4:23but I have the browse through, and that is this one here.

4:26So in my case, that's going to be 192.168.31.128.

4:33Now, that almost certainly is going

4:34to be a different IP address than what you'll get.

4:36Basically, whatever IP address you get,

4:38this is what you want to type into your browser.

4:41OK, so again, let's open up our browser,

4:43and let me type the IP address in.

4:45So I'll say http://192.168.31.128.

4:51Hit Enter.

4:52And now its going to take me to an EVE login page.

4:55Now, the user name here is not going to be root.

4:58Instead, it's going to be the word admin.

5:00But the password is still going to be eve.

5:04So let's type in those credentials then.

5:06So I'll say admin, and the password is eve.

5:08Now, as far as this part here, we

5:10have an option to choose a native console or an HTML5

5:13console.

5:14Basically, choosing the native console,

5:17that's going to allow you to access

5:18your devices over your favorite SSH terminal client

5:21such as maybe say PuTTY or SecureCRT.

5:25However, if you choose the HTML5 client,

5:28you can actually manage your devices just

5:30via a web browser tab.

5:32Now, I personally like to use the native one,

5:34because I do like to use PuTTY myself.

5:36But if you don't have anything installed such as PuTTY

5:39or SecureCRT, using the HTML5 client

5:42is a really handy way to be able to manage your devices.

5:45So from now, let's go for the minimalist approach,

5:47and we'll just choose HTML5.

5:49And we'll sign in.

5:50OK, so we click Save.

5:52Now, if we go over to this icon here, Add a New Lab, let's

5:56click on this.

5:56And what we can do is give our lab a name,

5:58and we'll just call this one test1 and click Save.

6:01And this is going to open up a workspace where we can actually

6:04begin adding devices.

6:06The problem is, is that we only have one device,

6:09and that is a VPC.

6:10So if I right click and choose Nodes, all of these devices

6:13are grayed out, as you can see, because of not being installed.

6:16But at the very bottom, we have a virtual PC.

6:19And if we right click this, Start, we

6:21could turn that device on.

6:22And we just click on the device.

6:23As you can see, it's opened up a connection

6:25within our browser tab.

6:27But like I say, this is super limited for us right now.

6:29We want to be able to automate in devices such as Cisco.

6:32So this requires that we install those images into our EVE-NG.

6:37Now, how exactly are we going to do that?

6:38Well, that is what we're going to be talking

6:40about in the very next Nugget.

6:41So I hope this has been informative for you,

6:43and I'd like to thank you for viewing.

0:00[MUSIC PLAYING]

0:10Hey, guys, and welcome back.

0:12So in the previous Nugget, we had just installed EVE-NG.

0:15The big problem, however, is that we didn't have

0:18any images installed just yet.

0:20And that's not good.

0:20However, we're going to solve that problem

0:23by installing our very first accessible images into our VM.

0:27So with that said, let's get to it.

0:29So if we open up our browser again, we go to Firefox.

0:31And what I'm going to search for a Cisco CML-P.

0:34That a Cisco Modeling Labs Personal.

0:36So if we go in here, click this link, what I'm going to do

0:39is go up to the top right hand corner here and choose Login.

0:42Now, if you haven't actually created an account with Cisco,

0:45you're going to have to create an account

0:47and just follow the process there as you it directs you to.

0:49In my case, however, I actually do have an account,

0:52so I'm going to log in with this.

0:53So I'll click Log In, and I'm just going to type

0:55in my email address and login.

0:57OK, so I've typed in my email and my password,

0:59so now I have logged in.

1:01OK, so if I scroll down a little bit here-- now,

1:04like I said at the beginning of the skill,

1:06in order to use the Cisco images,

1:08you're going to have to pay for this product.

1:10So if you haven't bought CML-P yet, then what you want to do

1:13is go to the personal?

1:14Option here, and click Buy Now.

1:16Now, the price is $199.

1:18I know that is not cheap, but I certainly

1:20do believe that, if you can afford it,

1:22it certainly is worth your while to purchase.

1:24Now, again, don't worry if you can't afford this.

1:27In the next Nugget, we're going to go

1:28through how to install Arista images for free,

1:32which pretty much have almost identical command line

1:35as do Cisco.

1:36Now, once you purchase this product,

1:38you're going to have a link to download CML-P. Now,

1:41within CML-P, built in, you're going to have these images.

1:45So let me show you what this looks like

1:47once you've purchased your product

1:48and have downloaded your CML-P.

1:50OK, so I have downloaded CML-P here within this folder.

1:54These are all the files which I need.

1:56Now, you actually have the CML-P Virtual Machine.

1:59This is an alternative to EVE-NG.

2:01But I personally prefer to use EVE-NG.

2:04All I really want from CML-P is access to the built in images.

2:08So how do we get the images from those downloads

2:11so that we can extract them and put them

2:13into our EVE-NG community edition?

2:15Well, see this option here down at the very bottom?

2:17Refplat-- if you re-click this and click Mounts--

2:21and what this is going to do is mount this on your DVD E drive.

2:24Now, within here, you're going to see a folder saying

2:26virl-base-images.

2:28If you click on this here, within this folder,

2:30we have all the images which we need.

2:32We've got the ASA firewall, we've

2:33got a CSR 1000v, IOSv, IOS layer 2 images.

2:38We have NXOS, so on and so forth.

2:41So to keep things simple, let me just drag these onto my desktop

2:45here.

2:45And I'll just drag three.

2:46I'll drag the csr1000v because this

2:49is the image we're going to be using later

2:51on within the course for NETCONF and RESTCONF,

2:54and I'll also pull my IOSv.

2:56This is my layer three router image.

2:58And I'll also take the IOS layer 2 image,

3:01which is our switch image.

3:02OK, so let me just close this now.

3:03So now we have these images dragged onto our desktop.

3:06So after we click one of these, here we

3:08have the qcow file, which is the file format

3:11that we're going to use for our EVE-NG.

3:13OK, now there's a few things that we

3:15need to install to get this up and running.

3:17The first thing we're going to install

3:18is something called PuTTY.

3:19This is going to be your SSH client, so let

3:21me go and install that first.

3:23So if you do a search for PuTTY and click the top link here--

3:26and what I'm going to do is click Download it here.

3:28So click this.

3:30Now, I've got a 64-bit machine, so I'm going to choose the top

3:32one--

3:3364-bit MSI installer.

3:34So if I save the file here and I go to my Downloads--

3:38let me just click this to open the file.

3:40It tells me this is an executable file.

3:42It may contain viruses, but this is a trusted source,

3:44so I'm going to say OK.

3:45And let's just go through the installation,

3:47which it will say Next.

3:48Where do I want to save it?

3:49I'll just keep on the C drive.

3:51And then I'll just select Install.

3:54OK, perfect.

3:54If I just click Finish, the PuTTY Readme pops up.

3:57Let me just close this.

3:58And then if I go the corner and I type PuTTY,

4:00we now have our SSH client.

4:02OK, great.

4:03So that's the first thing we're going to install.

4:05The second thing is going to be something called WinSCP.

4:08Let's go and install that then.

4:10So if you Google for WinSCP, click the top link,

4:13and then just click Download Now and then Download WinSCP.

4:17Click this link here.

4:18And it's going to pop up with a Setup.exe.

4:21Let's save this file.

4:22And if we go to our downloads-- we have it.

4:24Let's click this open.

4:25Now, what I'm going to say is Install For All Users.

4:27I'm going to accept the license agreement,

4:29and I'm going to choose a typical installation.

4:31This is the recommended installation,

4:33so I'm going to click Next.

4:34User interface-- I'll say Commander, and I'll go on Next.

4:36Finally, we'll choose Install, and everything

4:39is going to install.

4:40OK, so I'll just uncheck the open Get Started page,

4:43and I'll launch WinSCP.

4:44Perfect.

4:45So next, as a client, we need to be

4:46able to transfer our images into our Virtual Machine.

4:49OK, so that's working, so let's close this down temporarily.

4:52And what we want to do is to make sure

4:54that our EVE-NG is turned on.

4:56OK, so as we can see, our EVE-NG VM is on,

4:59and we know the IP address for my VM is 192.168.31.128.

5:04OK, so what I want to do is set for PuTTY, open that up,

5:08and then I'm going to type in the address of my EVE-NG.

5:10So that's 192.168.31.128.

5:14I'm going to be connected over port 22 because it's SSH,

5:17and I'm going to choose the connection type as SSH.

5:20Now, if I click Open--

5:22now, previously, because I had an old machine which

5:24I removed so that I could demonstrate this installation,

5:28I've got an actual conflict of keys effectively saying

5:31that, this IP address SSH key is actually changed.

5:35That's fine.

5:36All I'm going to say is Accept because this is what I expect.

5:38OK, so what am I going to log in as?

5:40We know the name is root and the password is eve--

5:43E-V-E. Hit Enter, and now we've logged into the machine.

5:47And what I also want to do is do the same thing on our WinSCP.

5:52So let's click WinSCP.

5:54The host name is going to be 192.168.31.128.

5:58It will be port 22.

6:00The user name is root, and the password is eve.

6:04If I click Login, do I want to Accept the key?

6:07I'm going to say Yes.

6:08And now it's going to log in, and now we

6:10can see we've actually logged in on the right hand side.

6:13This is the EVE-NG machine.

6:14On the left-hand side, we have my actual machine.

6:17OK, perfect.

6:18So what I want to do now is to open up a web browser,

6:21and what I'm going to search for is EVE-NG virl

6:24and then click this top link here, Cisco vIOS from VIRL,

6:27and I'm going to follow this process.

6:29The first I'm going to do is install the layer three image.

6:32So what I'm going to do is just copy this command here--

6:34mkdir to make it the directory for our layer three image.

6:37Copy this.

6:38And if I go to my PuTTY and paste this in, hit enter,

6:41now I've created this directory.

6:43So now this directory exists--

6:44vios-adventerprise.

6:46What I want to do is to transfer my layer three

6:49image into this directory.

6:51So what I can do is do that on WinSCP.

6:53So remember, I moved my images onto the desktop and my layer

6:57three images-- this one here, IOS.

6:59OK, so on the right hand side, I want

7:00to move to this new directory.

7:03So the path is opt, unetlab, addons, qemu,

7:08and then the name of the folder here, vios-adventerprise.

7:12So let's follow that path.

7:13We'll go to opt, unetlab, addons, qemu,

7:17and there's this folder we just created.

7:19Let's click on this.

7:20And what I want to do is just copy these two here

7:23and drag them into this folder.

7:25And I'll just say OK.

7:26And then it's going to move these files over.

7:28So now if I go back to my directory-- and let

7:30me cd into this directory here.

7:32Enter, enter.

7:33If I do an ls--

7:34and now we can see those two files have

7:36been copied from my desktop, and I'm now within the VM.

7:39So let's go back to our browser.

7:40And what I need to do here for my Cisco vIOS

7:43images is change these file names to be virtioa qcow2.

7:47So now I'm in this directory, what

7:48I want to say is mv to move this file

7:51and change the name to virtioa.qcow2.

7:55So hit Enter.

7:57Now, if I do an LS, that file name has been changed to this.

8:00And this is crucial.

8:01And now what I want to do is fix the permissions.

8:03So if I copy this command here-- copy you-- and just paste

8:07that command and hit Enter.

8:08Perfect.

8:09So now if we go back to EVE-NG and I log in with admin eve,

8:13I can now use a native console because I have PuTTY installed.

8:16Just sign in.

8:17Now, if I right click and choose Nodes, if I scroll down,

8:20I'm going to see a blue Cisco vIOS Router.

8:23That is not grayed out anymore.

8:25It's now accessible.

8:26And if I just click Save, that device is going to be present.

8:29So let's do the same for the layer switch

8:31as well as the ciosrv router.

8:34OK, so let's go back.

8:35If we scroll on down--

8:37and what I want to do here at part two

8:40is to copy this folder.

8:42I'll say mkdir, and this is for viosl2 this time.

8:46OK, so let me just cd back to my main directory.

8:48And what I am going to do is paste this in

8:50to create this other directory.

8:52So now if I go back to WinSCP and I click here

8:54to go back out a directory, now you

8:57can see we've only still got that one folder showing up.

9:00That's because our page hasn't refreshed.

9:02So if I click this green icon here to refresh the page,

9:04do that, there's that second folder we just created,

9:06and this is for our L2 images.

9:08Let's click in here.

9:10And what I want to do is go back out a directory,

9:12and I'll go into the L2 images.

9:14And let me drag these two over--

9:16copy you.

9:16Now, again, we have to change the name from vIOS,

9:19so let's go into that now.

9:21Go back to PuTTY, and I'll just cd into this directory-- cd,

9:24and I'll copy you.

9:25OK, so we've done LS.

9:27What I want to do is change the name of this file here.

9:30So I'll say mv and take in the name of the file, tab that out,

9:33and then I'll say virtioa.qcow2.

9:38Hit Enter-- if I do an LS, that has now been changed.

9:42So now what.

9:42I want to do here is to fix the permission.

9:44So if I just up arrow to get to that same command--

9:47there it is.

9:47They're opt, unetlab, wrappers, unl wrapper, -a fixpermissions.

9:51Hit Enter.

9:51And now our layer two image should now be accessible.

9:54Let's go back to EVE-NG, right click, go to Nodes.

9:57Now we can see the vIOS switch is also in blue.

10:00That's accessible.

10:01So let's save this.

10:02And lastly, let's do the CSRv Router.

10:04So, if you see, that's for EVE-NG CSR.

10:06It's going to take you to the EVE-NG website.

10:08So let's copy this.

10:10Now what I'm going to do is scroll down to state 8,

10:12and I'm just going to copy this part here.

10:14Copy you.

10:15OK, let's cd back-- pwd.

10:18I'll just clear the screen.

10:19And what I'll do is I'll paste this in

10:21to create a new directory.

10:22Perfect.

10:22So again, let's go back to our WinSCP.

10:25R we arrow up to go out the directory

10:28and we refresh the page, we now have our third folder.

10:31Let's go back to our desktop here,

10:33and we'll go into the CSR1.

10:35And we'll go into the CSR here, and all

10:38we do is copy these and pull them over as well.

10:41So now we're transferring the CSR

10:42from our desktop into our Virtual Machine once again.

10:45So let's cd into this directory here--

10:47copy this, hit Enter.

10:48We'll do an ls.

10:50And what I want to do is mv csr1000 universal,

10:54and we'll just tab this.

10:55And again, we'll do virtioa.qcow2.

10:59Perfect.

11:00Clear you.

11:01And if we just fix permissions, just arrow up.

11:03OK, opt, unetlab, wrappers, unl wrapper, -a fixpermissions,

11:07hit Enter and bam!

11:08That should be our three devices within our EVE-NG,

11:11and they all should be able to boot up correctly.

11:13So let's go back and test these out.

11:15So I'll just right click and turn off VPC.

11:17In fact, I'll just delete this-- get this out of the road.

11:19So what I'll do is go over to the left hand side,

11:21click More Actions, and click Start All

11:23Nodes to start the switch and the regular router.

11:26Now, these should take a few minutes to actually boot up.

11:29Just give it a little bit of time.

11:30OK, so I've waited a few minutes to let them boot up.

11:32What I'm going to do it just click on one of these devices.

11:35I'll click this one.

11:36Now, if it's not naturally finding PuTTY,

11:38then you're going to have to go in and manually choose it.

11:41In my case, it's finding it OK.

11:42So what I'm going to say is just Open Link.

11:44And if I just hit Return, we now have our switch here.

11:47Enable, Show, Run.

11:49Simple as that.

11:50So that's our switch up.

11:51If we go here and click on the router--

11:54and what I'm going to do is just check this box

11:56so it always opens it with PuTTY.

11:57Choose application, PuTTY, Open Link, Hit Return--

12:01I'll just say no.

12:02And there we have a router image again.

12:04We'll just do Show Version.

12:05All our commands are available to us.

12:07So just close this down, and I'll shut these off.

12:09And the last one I'm going to check

12:10is going to be the CSR image.

12:12Now, this image is a little bit more heavy weight.

12:14It takes more resources.

12:16And this is the image we're going

12:17to using later on in the course when we're dealing with NETCONF

12:20and RESTCONF.

12:21Let's go on to Nodes, and we'll choose Cisco CSR.

12:24And I'll just do Save.

12:26Now, if I right click, go on to Start,

12:28and give this a few minutes again to boot up--

12:31OK, so a few minutes have passed.

12:32Let me click on CSR, hit Enter, just say no.

12:36Hit Enter again, hit Enter one more time, and perfect!

12:39It looks like this image is also working.

12:41So there we have it.

12:42We now have our Cisco images up and running within our EVE-NG.

12:46This is going to allow us to build

12:48Cisco topologies-- topologies which we can then later

12:51automate.

12:52But like I said, these images do have to be purchased.

12:55So perhaps you can't afford to spend

12:56$199 on this Cisco license.

12:59So what I want to do now is to present a second option

13:02to you-- an alternative.

13:03And that is what we're going to be

13:04doing in the very next Nugget.

13:05So I hope this has been informative for you,

13:07and I'd like to thank you for viewing.

0:00[AUDIO LOGO]

0:10Hey, guys, and welcome back.

0:11So in the previous Nugget, we had just installed our Cisco

0:14images into an EVE-NG.

0:16In this Nugget, what we're going to do

0:17is to download the free Arista images and install them also.

0:22This is a really great alternative

0:23if you can't afford to buy those Cisco images.

0:26OK, so let's get to it.

0:27The first time we are going to do again

0:29is to open up our web browser.

0:30Now, if you just search for Arista login--

0:33let's go and click this top link here.

0:35Now, these images are absolutely free.

0:37They're not going to cost you anything.

0:38But you do have to create an account.

0:40If you don't have an account, then you're

0:42going to have to first specify that you need a User Account.

0:44Click this link here, and then follow all this information.

0:48Once you've done this, you will eventually

0:50receive an email with information

0:52about how to log in, which is what I've done.

0:54So what I'm going to do is go back,

0:56and I'm going to log in with my login information.

0:58OK.

0:59So now, I've logged in.

1:00It says Welcome John at the top.

1:02So what going do now is scroll down

1:04to the very bottom of this page here.

1:06And what I want to do is select Software Downloads

1:09at the very bottom here.

1:10So click this link.

1:11OK, so let's scroll down a little bit here.

1:13Now what I want to do is expand this one here, vEOS-lab.

1:17Just push the plus sign here.

1:18OK.

1:19So what I want to do is expand this Bit.

1:22And I'm going to click this one here.

1:23Aboot-veos-serial-8.0.0.iso.

1:27Lets click this.

1:28And what I want to do is save this file.

1:30So, OK.

1:30And this is going to download.

1:32Similarly, what I'm going to do is going to 4.26--

1:35expand that one.

1:36And then I want to download as the VMDK

1:39image, which is this here.

1:40So I click this one here.

1:42Again, we want to save this.

1:43And these are going to be downloaded.

1:45Case you know they've been downloaded,

1:47I've moved the Aboot image as well as the vEOS image

1:50onto my desktop for easy access.

1:53What I'm going to do is the same type of thing

1:55we did with the Cisco images.

1:56So the first thing I'll do is if I go back to my web browser,

1:59and if you search for EVE-NG Arista--

2:02let's click on this top link here.

2:04And what I'm going to do is copy this here and kit out

2:07and make that directory for the Arista images.

2:10So copy you.

2:11And then I'll open up PuTTY once again.

2:13Let me log in to my EVE-NG so 128,

2:15it's port 22, SSH and click Open.

2:19The log in is root and eve is the password.

2:22So let's paste this in to create this directory.

2:24Perfect.

2:25And now what I'm going to do is to go back to WinSCP and move

2:28these images into this folder.

2:30So WinSCP-- let's log in with address 192.168.31.128, port

2:3622, username is roots and password is eve.

2:40Let's click Login.

2:40So let's go to opt, unetlab, addons, qemu, and then

2:46go into veos--

2:47this folder we've just created here.

2:49Now, again, for easy access, I moved those images

2:51from my Downloads onto my Desktop.

2:53So what I want to do is to move these over.

2:56So I'll drag the Aboot image into this folder,

2:58and I'll say OK.

3:00And I'll drag the vEOS into the same folder,

3:03and this is going to copy on over.

3:05So what I'm going to do here--

3:06I just minimize this.

3:07And what I'm going to do is copy this part here--

3:11opt qcow.

3:12So copy here.

3:13And let's cd enter this directory.

3:15So cd/opt/unetlab/addons/qemu/veos.

3:20Now, let's paste this command.

3:22And then if I type vEOS and just tab the rest out

3:26to get the image.

3:27And then I'm going to say hda.qcow2.

3:31Hit enter.

3:32Case [INAUDIBLE] ls.

3:33OK, so now what you want to do is remove this VMDK image.

3:37We no longer need that.

3:38Now, we've created the qcow from it.

3:39So let's remove this ls.

3:41And what I want to do is mv the Aboot image,

3:45and call it cdrom.iso.

3:47So [INAUDIBLE] ls These images are now called this.

3:51And again, we want fix our permissions.

3:52So let's copy here.

3:54And we'll just paste this in.

3:55Hit Enter.

3:56And that should be it for Arista images.

3:59So if we go back to EVE-NG--

4:01let me right click.

4:02Choose Nodes.

4:03And now, we have Arista vEOS.

4:06If choose Save and if I right click and push start,

4:10that should turn on.

4:10Give it a few minutes.

4:11So once a few minutes have passed,

4:13let's click on the Arista Image.

4:15Hit Enter.

4:15OK, localhost log in.

4:17So the log in is just the word admin.

4:18Hit Enter.

4:19And now, we've logged in.

4:20And you're going to see this is super, super similar to Cisco.

4:24So if, for example, I click en, it takes me to Enable Mode.

4:27Now, the first thing I want to do

4:29is type zerotouch cancel because Arista

4:32is going to try to do something called Zero Touch Provision.

4:35If I hit this, that's going to reload the switch.

4:37And then once it comes back up, it's

4:39going to not attempt to do Zero Touch Provision.

4:41It's just going to act regularly.

4:43OK.

4:43So a few minutes have passed.

4:45Let's reload and let's type admin.

4:46And I just want to quickly highlight just

4:48how similar this image is to using Cisco.

4:51If we want to configure something, we will say enable.

4:54Then conf t.

4:55Then we can say something like router ospf 1.

4:58And then say router id 1.1.1.1.

5:01We can say network 192.168.1.0 with a welcome mask

5:06of 0.0.0.255 area 0.

5:10We can go back out and say show run.

5:12We can say show IP int brief.

5:14We can say show version.

5:15So again, if you don't have the ability

5:17to pay for the Cisco images, sign up for Arista,

5:20download these free images, and you'll

5:22be able to effectively follow on the labs no problem at all.

5:25So there you have it.

5:26There's your free alternative to be

5:28able to build a network and topologies.

5:30Topologies, which we can then use to practice our automation.

5:34OK, I hope this has been informative for you,

5:36and I'd like to thank you for viewing.

0:00[CBT NUGGETS JINGLE]

0:10Hey guys, and welcome back.

0:11So in the previous Nuggets, we had just installed EVE-NG,

0:13we added those Cisco images, and as an alternative,

0:17we also added the rest of the images.

0:19Now what we want to do is to focus on our development

0:22environment where we can install our automation tools.

0:25What we're going to be doing is installing an Ubuntu server

0:28within our VMware virtual machine.

0:30So let's roll up our sleeves and get going.

0:32So again, let's go to our browser,

0:33open up Firefox, and if you just search for "Ubuntu download,"

0:37click the top link here.

0:38We'll accept all and visit the site.

0:40Now, this is the version which I'm going

0:42to recommend you download--

0:43Ubuntu 20.04.2.0 Long Term Support.

0:47This is the version I'm going to be using.

0:49So this is the version I would probably

0:51recommend you go with, too.

0:53So what we want to do here is click on Downloads

0:55and just click Save File and OK.

0:58OK, so I've downloaded the image and I put into this folder

1:00called Ubuntu image.

1:02What I now want to do is to open my VMware

1:04and to create this virtual machine using this image.

1:07So let's open up VMware.

1:09What I want to do this time is to create a New Virtual

1:12Machine.

1:12And what I want to do is to browse

1:14to whatever this image is.

1:15So in my case, it's selecting the right image here,

1:18but if it isn't, just click Browse

1:19and go to the correct path.

1:20OK, so what I'm going to say here is Next.

1:23OK, so all I'm going to do is give my VM a name.

1:25I'm just going to say ipvzero, and the username,

1:28I'll just call it ipvzero again.

1:30And then give the VM a password.

1:31This will effectively be your pseudo password.

1:34And just confirm it.

1:35Click Next.

1:36So what is the VM name?

1:37Just call it anything you want.

1:38I'll just call this Automation Ubuntu.

1:41Or anything you want, really, will work.

1:43Now again, I'm running low on my C drive,

1:46so I'm going to actually install this into my D drive.

1:49So I'll go to Browse and I've actually

1:51created a folder called Automation Ubuntu,

1:53so I'm going to go to my D drive here and go into Automation

1:56Ubuntu and just click OK.

1:58OK, so I'm going to say Next.

2:00What is the maximum disk size?

2:01And if you want, I'll just give it 30

2:03to give it plenty of space.

2:04Just say Next.

2:05Now again, here is the options that's been given to me,

2:07but you can customize this if you want.

2:09If you have more memory, then you can kind of

2:12mem it up as high as you want.

2:13I'm just going to leave it at 4 gigabytes.

2:15The network adapter, again, is going

2:17to be NAT, the same as what we have for our EVE-NG.

2:20OK, let's go Close and I'll just say Finish.

2:22That looks OK to me.

2:23And what this is going to do is go

2:25through a basic automated easy installation of this Ubuntu

2:29server.

2:30So all we really need to do right now

2:31is sit back for maybe five, 10, 15 minutes,

2:34however long your computer takes, to create this image,

2:36and then once it's done, we can go in and begin

2:39setting things up.

2:40OK, now once that's done, you should see a screen just

2:42like this.

2:43What I'm going to do is just click on this.

2:45This is my username.

2:46And I'm going to type in the password which

2:48I created at the very start.

2:49Hit Enter, and it's going to log me in.

2:51All I'm going to do is click Skip here, and Next, Next,

2:54Next, and then Done.

2:56Now, the software update that has come up,

2:59I'm just going to say Remind Me Later,

3:01and then I'm going to go down to the bottom left hand

3:03corner here, click this, and then

3:05I'll just search for Terminal.

3:06Hit Enter, open my terminal up.

3:08OK, now to make this a little bit easier to read,

3:10I'm going to go here, click on Preferences.

3:13I'll go down to Unnamed, I'll choose Custom fonts.

3:17I'll maybe choose something like Noto Mono Bold

3:20and I'll auto up.

3:21And I'll use a plus sign to make the text a little bit bigger

3:24and easier to see.

3:25Hit to Select and just Exit out of this.

3:27OK, so what I want to say here is sudo apt update,

3:30and I'll type in my password, and I'll say sudo apt

3:33install openssh-server.

3:37Hit Enter and push Y. Hit Enter again.

3:41OK, now what I also want to say is sudo apt

3:43get install python3-venv.

3:48Hit Enter, push Y, hit Enter again, perfect.

3:50And for the moment, this is all we need for our Ubuntu server.

3:54So the next thing we're going to do

3:55is to be able to install a VS code, which

3:57is going to be our integrated development environments.

4:00And this is where we're going to do all of our coding

4:03for all of our network automation.

4:04That is coming up next, and I hope

4:06this has been informative for you,

4:07and I'd like to thank you for viewing.

0:09Hey guys, and welcome back.

0:11So in the previous Nugget, we had just

0:13installed our Ubuntu server, which is going

0:15to be our automation system.

0:16And in this Nugget, what we're going to do

0:18is install VS Code, which is going

0:19to be our IDE for development.

0:22Now, I'm going to present to you two ways in which you

0:24can install VS Code.

0:26You can do it locally on the machine

0:27here and login to the VM.

0:30Or you can install VS Code directly on the VM.

0:33I'm going to show you both ways, and you can

0:35choose which way you prefer.

0:36OK.

0:37Again, so what I'm going to do is go to my browser just now.

0:39And if I go to Google and just type VS Code,

0:42let's click the top link here.

0:44And what I'm going to choose is Download for Windows.

0:47We're going to get this link.

0:48Just click Save.

0:49And now this is downloaded, let's click this to open it.

0:52And I'm going to Accept the Agreement.

0:54Click this, and choose Next.

0:56Now, where do we want to install VS Code?

0:58Again, I'm going to move onto my D drive.

1:00But if you want to leave it onto your C drive,

1:02that's perfectly OK.

1:03So I'll scroll down, go to D drive.

1:06And I've got a folder called VS Code here created.

1:08So I'll choose OK, and select Next, choose Next again.

1:12And what I'll do is I'll choose the create a desktop icon.

1:15And I'll also select these options here to open with code.

1:18Just choose Next, and click Install.

1:20And VS Code is going to be installed into your machine.

1:23And that is all, so click Finish.

1:25And now VS Code is going to launch.

1:27OK, so what I'm going to do is suggest to you

1:30some of the extensions I feel that you should install.

1:33This is just going to make your life easier,

1:35and VS Code has a ton of cool extensions.

1:37So let me show you which ones I use.

1:39So let's just maximize this for now.

1:41If you to File, go down to Preferences,

1:44and then choose Extensions.

1:46Now, here are some of the extensions

1:48which I've installed.

1:49And you can just search for them here.

1:51So the theme I'm going to choose is Monokai Pro.

1:53So just click on this.

1:54Now, I'm going to suggest that you, perhaps,

1:56also use this theme, although you don't have to.

1:58But it will make it a little bit easier,

2:00because it means you're going to have

2:02the exact same color highlighting

2:04as I have on my screen.

2:05It will just make it easier to follow that you're

2:07typing the right thing.

2:08But if you want to choose another theme, say,

2:10for example, One Dark Pro, you can click on this, and just

2:13click Install.

2:14But in my case, I'm going to choose Monokai Pro.

2:17So let me just set the color theme, and choose Monokai Pro.

2:20So let me just move this back, delete this.

2:23Now, you certainly want to search for Python,

2:25and click Python here.

2:26This is going to give you IntelliSense,

2:29which is effectively all of your auto completion.

2:31So do you know what?

2:32I'll just uninstall this so I can reinstall it for you.

2:34So all you would do would be super simple.

2:37Just search for Python, and then click Install here.

2:41That's going to install it, simple as that.

2:43Now, the other one is Better Jinja.

2:45I would suggest you get this one.

2:47Again, I'll uninstall it just to show you.

2:49Again, all you need to do is click Install,

2:51and that's going to install.

2:52And the last one is this one here, Cisco iOS Syntax.

2:56I would suggest you search for this and also install this.

2:59We'll certainly be making use of these extensions

3:01throughout the course.

3:02OK.

3:02Now, the really important one, which

3:04I'm going to suggest you install,

3:05and this is needed to be able to login to our Ubuntu VM,

3:10is something called Remote SSH.

3:11And I found this one by review in a fallacy

3:13between Ogletree and Trevor.

3:15Trevor recommends this all the time,

3:16and I must say he was bang on the money with it.

3:18So if you just go here, and click Install for Remote SSH,

3:22now we also have the Remote SSH extension.

3:26OK, so now that we have the Remote SSH extension installed,

3:29here is what we're going to do.

3:31Let's go back to our Ubuntu VM and get the IP address.

3:34I'll just minimize this, move this over a little bit,

3:37and I'll go into my Virtual Machine

3:39here, type in the password.

3:40I'll just full screen this to make it a little bit easier.

3:43Clear the screen, we'll do ip adder.

3:45And here is the IP address.

3:47Here, 192.168.31.129.

3:52So what I want to do is to be able to login to this Virtual

3:55Machine using my Remote SSH from VS Code.

3:58So let's close this again.

4:00And what I want to do is, on the left hand side here,

4:02we see a Remote Explorer.

4:03If we click on this, what I want to do is select SSH targets.

4:08Now, I've already got a target here from a previous session.

4:10I'm just going to add a new one.

4:12And all I'm going to say is, SSH,

4:14and my username is ipvzero.

4:17And I'll do @ and type in the IP address 192.168.31.129 it was.

4:23And hit Enter, and hit Enter again.

4:25And its saying host has been added.

4:27OK, so what I'm going to do is right

4:28click this and Connect to Host in Current Window.

4:32And I'm going to choose the platform as Linux.

4:34It'll show me the SSH fingerprint.

4:36I'm going to say Continue.

4:37I need to enter the password.

4:39So I type in the password I created for that VM, which

4:42is the sudo password.

4:43Type it and hit Enter.

4:44And now, look at that, we've actually logged into the VM

4:48directly from Windows.

4:49So if we do an LS, we now have access to that VM

4:52directly from our VS Code.

4:54And what I can do is develop here.

4:56So if I want to create a new file, I can just say New File.

5:00And let me just Save this As.

5:01And you'll notice that it actually saving it

5:03within the path of the VM.

5:05Look all these folders.

5:06This is my Linux environment here.

5:07So let me just create a file, just called test1.py,

5:11hit Enter.

5:11And at the bottom right, its saying,

5:13do you want to install the recommended

5:14extensions for Python?

5:15We're going to say Install.

5:17Now, we need to reload the window for py lines to work.

5:19Now, because its reloaded, I've been

5:21prompted to re-enter the password for the VM.

5:23So I'll type in that password once again at the top, hit

5:25Enter.

5:26OK, let me just move this over here.

5:28And what I can say is, for i in range.

5:31And you can see, we've got all the auto-completion good

5:33on here.

5:34Just say 0 to 11, and we'll just print i.

5:38And if I push Control S, that's going to save the file.

5:41And here's the thing, if we go down to the terminal here,

5:43we do an ls.

5:44Look at this, we now have a new file here, test1.py,

5:47that's now being created from our Windows development box,

5:51directly onto our Ubuntu VM.

5:54So on this terminal down here, I can just

5:55say python3 test1.py, hit Enter.

5:58And its going to execute that script.

6:00So this is how we can install VS Code locally on Windows

6:03and just SSH into the VM.

6:07Now, if you don't want to do it this way,

6:08you can just directly install VS Code right onto the VM.

6:12So let me show you how you can do that as well.

6:14So let me just Minimize this.

6:15Let's open up the VM, and let me just login.

6:18And again, just before we install VS Code locally,

6:20if we do an ls, look here, we've actually

6:23created that test1.py file from our Windows machine.

6:26And you can just execute it from here,

6:28and there's that code there.

6:30OK, so what we're going to do here to install VS Code,

6:32we're going to use the Snap package manager.

6:34So what I'm going to say is, sudo snap install, dash

6:37dash, classic code.

6:39And I hit Enter, type in my password.

6:41Nope.

6:42Type in the password correctly, that would help.

6:44And now, it's going to install VS Code for us.

6:46Perfect.

6:47Now, the way we can open code is just type in the word code

6:49now, hit Enter.

6:51And that is going to launch Visual Studio Code.

6:53So now, we have the exact same platform directly

6:56installed on our Ubuntu VM.

6:58And we can create files just the same way.

7:00Create New File, Save it As.

7:02And let's just call this one test2.py.

7:04And again, in the bottom here, we want to click Install.

7:07And again, we want to install all of our extensions.

7:10Now, it's seen here, no Python interpreter is selected.

7:13So if you get this problem, we need

7:15to select the Python Interpreter.

7:16So just click this, and we're going to choose,

7:18in this case, then Python3.

7:20And then I'll reload the window.

7:22Perfect.

7:23And again, just the same as before.

7:24And before I do anything, what I'm going to say

7:26is going to Settings, Preferences, Settings.

7:29And I'll change the font size to be a little bit bigger

7:31so its easier to see.

7:32Let's choose 24.

7:33OK.

7:34And again, what I want to do is use Monokai Pro for the theme.

7:38Let me just Install this, perfect.

7:40Click on this here.

7:41And again, what we can say is print, I love CBT Nuggets.

7:45Control S to Save.

7:47If we go back to our terminal, we do an ls,

7:50we have our test2.py file.

7:51Let's just run it.

7:52And there we have it.

7:54So we've seen how we can install VS Code directly onto Windows.

7:57And we can Remote SSH into our Ubuntu system.

8:00Or alternatively, if you find it easier

8:03just to install VS Code directly on the Linux box,

8:06you can do that too.

8:07Which one is better?

8:08Well, there really isn't a better one.

8:10Whatever you prefer is OK.

8:12So now that we have our Eve-NG running,

8:14we have our images installed, we have a development environment,

8:16and our Ubuntu box set up.

8:18Let's see how we can build a simple topology within Eve-NG

8:22and reach those machines from within this development

8:24box on Ubuntu.

8:25And that is what we're going to be

8:27doing in the very next Nugget.

8:28So I hope this has been informative for you,

8:30and I'd like to thank you for viewing.

0:09Hey guys, and welcome back.

0:11So in the previous Nugget, we had just

0:13installed VS Code within our automation system or Ubuntu VM.

0:17Now, what we want to do is to be able to build a topology

0:20and be able to reach those devices from that automation

0:24system.

0:25Let's see how we can do that then.

0:27OK, so let me just open back up this virtual machine.

0:30And what I'm going to do is also right click on this VMware

0:34and choose another VMware.

0:36And what I want to do here is switch on the EVE-NG.

0:38If you click on this, and Play this virtual machine.

0:41So we have both of the VMs up and running,

0:43EVE-NG on the left and our Ubuntu on the right.

0:46OK, so I'll just say root Eve, and let's go

0:48to our browser and browse to the EVE-NG address of 128.

0:52OK, so let's login.

0:53OK, so from now what I want to do here, is just right click,

0:56and I'll choose two nodes.

0:58And what I'll do is, I'll take an Arista device so you

1:00can see how that is done.

1:01And I'll also take a Cisco Router and Save here.

1:05And I'll also take a Cisco Switch.

1:07This can just be my out of band Management Switch here.

1:10I'll choose Switch, and I'll just change the icon here.

1:13You don't have to do this, but I'll just

1:14change it to another icon.

1:15So it's that out of band one, and I'll change the name

1:18to Management Switch.

1:19OK, so let me Save this.

1:21So this is going to be my Management Switch.

1:23These two devices are going to be the actual network which

1:25I'm trying to reach.

1:26So what I want to do, in the case of the Cisco device,

1:29just connect it to one of the interfaces.

1:31So in this case, I'm going to connect

1:32from g0/0 to g0/0, that's fine.

1:35Now, in the case of the Arista device,

1:37that actually has a Dedicated Management Interface,

1:40which actually saves us a little bit of configuration.

1:42It's quite cool.

1:43So connect this, and instead, we want

1:45to choose the MGMT1 interface.

1:48And let's just also connect these two devices together.

1:51Let's pretend this is the actual network.

1:52So we'll just do Eth1 here to g0/1.

1:55That'll do fine.

1:56Now, the way we can reach into this VM, what we have to do

1:59is right click, and choose Network.

2:01And we need to choose ManagementCloud0.

2:04So if we Save this and connect this to our Management

2:08Switch here, and push Save.

2:10What I'm going to do is just say More and Start All Nodes.

2:13I'll give this a few minutes to let them boot up.

2:15OK, so let's go into the Cisco device first,

2:17and I'll hit Enter.

2:18I'll say No.

2:19OK, so I'll say Enable will give our device a hostname.

2:22So I'll just say hostname and just call it CiscoRouter.

2:26I want to give a username.

2:28So I'll say username john, which is my name.

2:30I'll say it privilege 15, and I'll

2:32say the password is equal to password1.

2:35I'll create a domain name.

2:37So I'll say, ip domain-name, and I'll just go with cisco.com.

2:41I'll say ip ssh version 2.

2:43I'll say crypto key, generate rsa, modulus 1024.

2:48I'll go into my vty line.

2:50So line vty 0 4.

2:52I'll say transport inputs ssh, and I'll say login local.

2:58Now let me just exit back, and I'll say vrf definition MGMT.

3:03I'll say address family ipv4.

3:06And then what I want to do is to go

3:08into my Management Interface.

3:09So in this case, this is going to be g0/0.

3:13So I'll say int g0/0.

3:15I'll say vrf forwarding and then the name

3:18of the vrf, which is MGMT.

3:20And now what I want to do is to create

3:22an out of band management IP address.

3:24Now, the management range I'm going to choose

3:26is going to be the same that is within this range up here.

3:29So within the 192.168.31.0/24 for me.

3:34So let's say, for example, your EVE-NG was 192.168.56.119,

3:40you would want to use the IP address space 192.168.56.0/24.

3:46Mine says 31, so I'm going to be using

3:48that for my management range.

3:50So I'll do ip address, 192.168.31,

3:53and I'll just say 101, and give it a slash 24 mask,

3:57and then say no shut.

3:59And if I just do wr to save this, that should be me there.

4:02So what I could do now is to ssh into this device from my Ubuntu

4:06machine.

4:07So again, you've got two options.

4:08You can use your remote ssh here to login

4:11or connect to host, type in the password for the Ubuntu

4:14machine.

4:14And now I'm inside the Ubuntu VM.

4:17I'll just login this way and use the terminal directly

4:19from the box.

4:20Whatever way you prefer is OK.

4:22So for simplicity, I'll just go directly to the machine here,

4:25and I'll maximize this to make it a little bit easier to see.

4:28Now, what I want to do is try to ping that machine.

4:30Now remember, if I do my IP address,

4:32we actually are on the same network.

4:34Can you see that?

4:35We're in the 192.168.31/24.

4:39This address happens to be 129, whereas my EVE-NG machine

4:43happens to be 128, and the Cisco box is 101.

4:48So if I do ssh, and the Cisco device has a username of john.

4:51And I'll do 192.168.31.101, hit Enter.

4:56Now look at this.

4:57This is a very common problem when using Cisco devices,

5:01because they use out of date ciphers.

5:03So the way we can fix this is say,

5:05sudo nano /etc/ssh/ssh_config, type in the passwords.

5:11And what I'm going to do here, I'm

5:13going to uncomment StrictHostKeyChecking.

5:16And I'll change this to No.

5:17These are some settings I like.

5:19I'll uncomment out these ciphers here and at the very bottom.

5:23Now, what I'm going to say down here is KexAlgorithms space,

5:27and then a +diffie-hellman-group14-shar1.

5:34And then if I press Control-O to write out

5:36and then Control-X to escape, clear here.

5:39Now if I try to login ssh john@192.168.31.101.

5:46Now, if I just take the password, which is password1,

5:49we have successfully logged into the device

5:51through ip int brief, and now we can reach our topology

5:54from our automation system, which means we can run scripts

5:58against our topology.

5:59So that was the Cisco device.

6:01How do we get access to the Arista device?

6:03Well, let's quickly do that as well.

6:05So I'll just exit out here.

6:06Now, Arista make it really, really easy.

6:08We don't have to configure a VRF because the management

6:11interface here is already within its own VRF.

6:14And the good news is, is the ssh is already enabled.

6:17The only thing we have to worry about here, is if we say admin,

6:20again we're going to say enable, and for the first time

6:23we're going to say zerotouch cancel, again.

6:25This is going to reboot the box.

6:27Once it comes back up, though, we're

6:28not going to have this issue.

6:30Just give us a minute or two to reload.

6:32OK, perfect.

6:32So I want to say admin again.

6:34To login, I'll just say enable, conf t,

6:37and we'll just say hostname.

6:39And we'll just call this one AristaRouter.

6:40Now again, we don't have to configure a VRF within Arista,

6:44and we don't have to enable ssh.

6:46All I'm going to do is create a username.

6:47So I'll say username john, privilege 15,

6:51and I'll say secret password1.

6:54There we go.

6:54And then what I want to do is to go

6:56into interface management 1, which

6:58is the management interface.

7:00And again, I want to give that an address

7:02within that same range.

7:03So my range is going to be 192.168.31, and then

7:07just choose an IP address.

7:09I'll say 102 for this one, and give it a slash 24 mask,

7:12and no shut it.

7:13And then what I can do is just Save this with the wr,

7:16and this has been successfully saved.

7:18Now again, if we go back to our Ubuntu VM,

7:21go back here, and just clear the screen.

7:23And if we just say ssh john, and then we do 192.168.31.102,

7:28hit Enter.

7:29Type in the password of password1.

7:31Now we have access to the Arista device.

7:33So show ip int brief.

7:35There we go.

7:36Show run.

7:37No problem at all.

7:38So because we have ssh access to these devices,

7:41we can now target them for automation, no problem at all.

7:44So this is how we can set up our configuration locally,

7:46where we can have devices local on a machine and our EVE-NG VM.

7:51However, but also as another option available to us,

7:54and that is in the form of the Cisco DevNet Sandboxes.

7:57And that is what we're going to be looking at next.

8:00So I hope this has been informative for you,

8:01and I'd like to thank you for viewing.

0:10Hey, guys, and welcome back.

0:11So in the previous Nugget, we had just

0:13set up our EVE-NG Topology on our local machine.

0:16Now, what we want to do is to be able to explore

0:19how we can access devices via the internet.

0:22So let's check it out.

0:23Let's open up a new tab here, and you just

0:25Google Cisco DevNet Sandbox.

0:28And just click this top link here.

0:30Now, you're going to have to sign up

0:31to be able to access these.

0:33I've already signed up, so I'm going to click login.

0:35But if you haven't, sign up for free here.

0:37So click login, and I'm just going

0:39to log in with my IP Visio GitHub accounts.

0:42OK, so what I'm going to do is get started by Sandbox.

0:44OK, now, here's the thing.

0:45There are two types of Sandbox.

0:47We have the Always-ON Sandbox, and we have Reservable Sandbox.

0:52The one we going to be exploring as Always-ON.

0:55The good news about this one is that it's always on.

0:57It requires no reservation at all.

1:00Anyone can access it at anytime.

1:02You don't have to book anything.

1:03You don't have to have a VPN connection.

1:06Your simple internet connection will

1:07be able to get you into the device quite [INAUDIBLE]..

1:09The limitation of using an Always-ON Sandbox

1:12is that you're just getting access to one device.

1:14So it's OK in a limited form.

1:16You can test out pushing some configurations to a device.

1:19Feel your automation system.

1:20But if you really want to automate it

1:22to a large topology, you're going

1:23to be want to use something, like EVE-NG,

1:26or perhaps, reserve an actual Sandbox.

1:29Because when you reserve a Sandbox,

1:30what you're going to be able to do

1:32is to access multiple devices.

1:33But for now, all we're going to be

1:35doing as looking at the easily accessible Always-ON Sandbox.

1:39So dependent on the type of device

1:40you want, you can look for an XE device.

1:43You can look for an XR device, or maybe, perhaps, you

1:45can look for an NX device.

1:47This is our Nexus devices for the data center.

1:50The reality is you can just browse through the Sandbox

1:52and find what you like.

1:54For an example, let me access an XE Sandbox.

1:57So I will just search for XE.

1:58These ones here are Reservable Sandboxes.

2:01This means you're going to have to download the Cisco VPN,

2:05and connect 10 via a VPN, and book a time slot.

2:08But in the case of the Always-ON,

2:09we can just access it directly from an internet connection.

2:12So let's just choose one of these

2:13then, so we'll choose the iOS XE CSR recommended Always-ON.

2:17Click this.

2:18And if we scroll down here, it's going

2:20to tell us the login details.

2:22So as opposed to typing a numerical IP address, if we

2:25just take this address here, and as opposed

2:28to accessing it over port 22, we're

2:30going to access over SSH 8181.

2:33If we log in with the name, developer,

2:35and the password, C1sco12345, with the number one as the I,

2:40we can access this Always-ON Sandbox.

2:43So let me show you this, so all I'm going to do

2:45is get out my virtual machine.

2:47OK, so let's clear here.

2:49And what I'm going to do is copy this address here, so

2:51copy here.

2:52And I'm going to say, SSH, and the login name

2:56is Developer, here.

2:57And just paste the address.

2:58And because it's not on the default port, or port 22,

3:01I'm going to have say, P8181.

3:04So if I hit enter, and I type in the password

3:07of C1sco12345 with a one for the I, so C1sco12345.

3:14Hit enter.

3:15Now, I've logged into this device,

3:17so I can say show IP int brief.

3:19I can say, show run.

3:20Scroll on through, and I can also configure things,

3:22like, say, router ospf 46.

3:25And if I just do a show run, that's

3:27now going to be configured on the box.

3:28Scroll on down.

3:30There, we can see a router ospf 46 is actually been configured.

3:33So this is a real easy way, where

3:35we can access to the device online and push our automation

3:38scripts to that device.

3:39And this requires no more setup than simply getting the login

3:43details and just ssh into that box.

3:46Now, all I will say is that not every box has

3:48the same credentials, so what you should do

3:50is look for each box individually.

3:52So if you go into an XR box, this

3:54is going to have a different login than, for example,

3:57this XE box.

3:58Same way with the Nexus devices.

4:00Okie doke, so I do think we now have some viable options

4:03to set up labs.

4:04We have all the building blocks in place

4:06to begin automating networks.

4:08So from now on, how about we start doing the fun stuff

4:10and begin automating?

4:12Well, step on ahead to the next skill.

4:13That's what we're going to be doing,

4:14and I hope this has been informative for you.

4:16And I'd like to thank you for viewing.
