Overview

After taking this course, you should be able to:
Describe the key concepts of segment routing
Implement and verify IGP segment routing
Migrate an existing Multiprotocol Label Switching (MPLS) LDP-based network to segment routing
Implement and verify TI-LFA segment routing
Instantiate segment routing policies
Instantiate multidomain segment routing policies
Configure and verify BGP prefix segments and SR-based services

The Implementing Segment Routing on Cisco IOS XR (SEGRTE201) v2.0 course 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).
