Implementing Segment Routing on Cisco IOS XR (SEGRTE201)

The Implementing Segment Routing on Cisco IOS XR (SEGRTE201) training covers the fundamental concepts of segment routing (SR), how to configure and verify segment routing within an Interior Gateway Protocol (IGP), and the interworking of Label Distribution Protocol (LDP) with segment routing. You will learn how to implement topology-independent loop-free alternate (TI-LFA) using segment routing, and how to instantiate and verify segment routing traffic engineering policies. You will also learn how to implement segment routing within Border Gateway Protocol (BGP).
