SR TI-LFA SRLG

Devices
EVE-NG: 6 x Cisco XRv 9k 6.5.3s

This lab showcases the use of TI-LFA with Shared-Risk-Link groups in a Segment Routing environment. SR is running on each device. Gi0/0/0/2 and Gi0/0/0/3 on R2 have been placed into the same SRLG. When considering R6’s loopback (10.1.1.6/32) as a destination you can see how FRR calculates the backup path using the show isis fast-reroute 10.1.1.6/32 detail command. This lab could also be useful for testing other types of SR TI-LFA solutions.
