SEGRTE201-Implementing Segment Routing on Cisco IOS XR

This course covers the fundamental concepts of segment routing, how to configure and verify segment routing within an Interior Gateway Protocol (IGP), the interworking of Label Distribution Protocol (LDP) with segment routing, how to implement topology-independent loop-free alternate (TI-LFA) using segment routing, and how to instantiate and verify segment routing traffic engineering policies. Students will also learn how to implement segment routing within Border Gateway Protocol (BGP).

This course is eligible for 32 Continuing Education Credits (ILT & ELT Modality).
