XR Segment Routing Bootcamp

Engineers that require a strong knowledge of Segment Routing and how to configure with Cisco IOS XR.

Attendees will learn how to configure and verify segment routing within IGP, understand and implement Topology Independent Loop-Free Alternate using segment routing, implement Segment Routing – Traffic Engineering, and implement segment routing within Border Gateway Protocol.
