Objective
The objective of this lab is to explore a scenario where TI-LFA is instructed to provide node protection, meaning the PLR calculates and installs a fast reroute path for a potential link failure to circumvent the entire router, not just the link. This is accomplished using the following tasks:
- Applying the configuration to enable TI-LFA node protection on
P2
- Verifying that the TI-LFA node protection backup path is computed and added to the RIB, FIB, and LFIB of
P2
.
Therefore, the next step involves configuring all routers in the network with MPLS traffic engineering to facilitate the deployment and operation of SRAT.
Note
For the purpose of this book, MPLS traffic engineering is not explored beyond the commands necessary to support auto-tunnels.
Let’s dive in!
