Implementing Segment Routing on Cisco IOS XR (SEGRTE201) Course Overview

Implementing Segment Routing on Cisco IOS XR (SEGRTE201) Course Overview

The "Implementing Segment Routing on Cisco IOS XR (SEGRTE201)" course is designed to provide network engineers and technicians with the knowledge and skills necessary to implement and manage segment routing within their Cisco IOS XR networks. The course covers a range of topics including Segment Routing (SR) and Label Distribution Protocol (LDP) interworking, SR policies for traffic engineering, Topology Independent Loop-Free Alternate (TI-LFA), and the use of various tools like Mapping Server Function, Path Computation Element (PCE), and BGP Link-State (LS).

Through a series of modules and hands-on lab exercises, learners will gain an in-depth understanding of how to deploy SR and LDP interworking, configure SR TI-LFA for both SR and LDP traffic, and implement SR policies using various approaches, such as Explicit and dynamic path options. Additionally, the course delves into Multidomain SR policies, BGP Prefix Segment, Egress Peer Engineering, and the use of BGP for data center interconnects.

By completing this course, learners will be well-equipped with the skills to enhance network efficiency, scalability, and reliability through Segment Routing, and be prepared to optimize their network's traffic engineering capabilities.
