IS-IS segment routing verification

“

- [Instructor] In this session, we will learn how to monitor and verify is-is segment routing. The show is-is adjacency detail command in Cisco iOS XR provides detailed information about is-is adjacencies, particularly useful in the context of segment routing. Adjacency segment identifier or SID. This is a unique identifier assigned to an is-is adjacency used in segment routing, or SR, to represent a specific link between two routers. The adjacency SID is essential for direct forwarding along a specified path within the network. Non-fast reroute, non-FRR adjacency SID. This is an adjacency SID that is not configured for fast reroute or FRR. FRR is a mechanism designed to quickly reroute traffic in case of a link or node failure, ensuring minimal disruption. Let's use the show is-is adjacency detail command on R1 to monitor and verify is-is segment routing. This command will provide detailed information about the is-is adjacencies, including adjacency SID and non-FRR adjacency SID…
