Objective
Continuing from the previous chapter, the topology already features local SRLG-disjoint protection. This lab’s objective is to explore a scenario where TI-LFA is configured to provide a node and SRLG-protected fast reroute backup path. The tasks outlined next accomplish this goal:
- Apply the
ti-lfanode protection configuration onP2 - Verify that the
node+srlgbackup path is computed and added to the RIB, FIB, and LFIB of P2.
The topology described in Figure 13.1 illustrates the TI-LFA Node + SRLG protection configuration.
Figure 13.1 – TI-LFA Node + SRLG protection
At the end of the previous chapter, the configuration on router P2 was changed to remove only the Global Weighted SRLG protection, while the local SRLG-disjoint protection remains configured.
