SP0023 - MPLS TE FRR Node Protection

The video demonstrates an ability to reroute traffic around a failed router (node) using Fast Reroute feature of Cisco MPLS Traffic Engineering. The concept is very similar to what we saw with Link Protection in the previous video except for the extra label communication from Merge Point (MP) router to Point-of-Local-Repair (PLR) router due to that fact that they are no longer directly connected, which will be elaborated in this video. We will go through the configuration and also perform failover test so you can see this in action.

SP0022 - MPLS TE FRR Link Protection

When you have a critical link that needs to be protected from extended packet loss, it is possible to pre-establish a MPLS TE tunnel (aka NHOP) routed around the link so traffic can be immediately rerouted after the link goes down, by simply start using the MPLS TE label instead of regular label, without having to wait for routing to converge. This method is known as Fast Reroute with Link Protection and we go through the setup and configuration in this video. We will also perform failover test so you can see this in action.
