Advanced MPLS
This Advanced MPLS Tutorial for Cisco Network Engineers training covers how to optimize traffic through particularly large or complex networks by configuring Multiprotocol Label Switching on network routers. Once a network gets complex enough — it needs a better way to direct traffic. One way is multiprotocol label switching. This can help with network efficiency so that only certain kinds of traffic use certain areas and low-urgency traffic can take longer, slower routes.
