Junos Segment Routing (JSR)


Course Overview

This one-day course is designed to provide in-depth instruction on segment routing, or Source Packet Routing in Networking (SPRING). The course focuses on the configuration of Juniper Networks routing and switching devices to support segment routing using MPLS switching. Topics include functional concepts, the configuration of the IGPs used to propagate label information within a domain, segment routing traffic engineering using BGP colored routes, and redundancy/high availability concepts including BFD, Topology Independent Loop-Free Alternative (TI-LFA), Anycast Segments, and the implementation of link aggregation in a segment routing design.

Who should attend

The primary audiences for this course are the following:

  • Service Provider design engineers
  • Campus and Enterprise design engineers


The following are the prerequisites for this course:

  • Understanding of the OSI model.
  • Advanced routing knowledge; the Advanced Junos Enterprise Routing (AJER) course or equivalent knowledge strongly recommended.
  • Intermediate knowledge of MPLS functions.
  • Intermediate to advanced Junos CLI experience.

Course Objectives

After successfully completing this course, you should be able to:

  • Describe and configure segment routing.
  • Describe and configure traffic engineering with segment routing static paths.
  • Describe and configure traffic engineering paths using BGP and colored route tags.
  • Describe and configure TI-LFA.
  • Describe and configure Anycast segments.
  • Describe and configure LAG in a segment routing design.
