Implementing Segment Routing on Cisco IOS XR

Course Duration

4 Days

Prerequisites

● Cisco IOS XR platform and command-line interface (CLI) familiarity
● Detailed knowledge of TCP/IP routing and switching design and configuration in a multilayer service provider network
● Understanding of Internal Gateway Protocol (IGP) operations for Intermediate System-to-Intermediate System (IS-IS) Protocol and Open Shortest Path First (OSPF) Protocol
● Understanding of MPLS, Layer 3 VPN, and BGP technology and implementation Recommended Prerequisites Cisco recommends that you have practical knowledge of service provider MPLS network design and implementation strategies.

Course Content

It covers 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. You will also learn how to implement segment routing within Border Gateway Protocol (BGP).

The Implementing Segment Routing on Cisco IOS XR course is designed for engineers and service providers who are deploying segment routing within their network.
