Junos Segment Routing for MPLS

This four-day, advanced-level course provides an in-depth introduction to MPLS segment routing (SR), otherwise known as Source Packet Routing in Networking (SPRING). It also includes two additional day’s worth of self-study material. The course focuses on the configuration of Juniper Networks routing and switching devices to support MPLS segment routing. After exploring the features and use cases for SR-MPLS, students are introduced to the building blocks of a segment-routed network (namely, adjacency segment identifiers (SIDs), node SIDs, prefix SIDs and anycast SIDs). The course includes these features for both IS-IS and OSPF.

Students then learn how to use these SIDs to create label-switched paths (LSPs) and tunnels within an MPLS network. This includes the creation of shortest-path LSPs, traffic-engineered SR policies with static paths, SR policies with dynamically calculated paths using distributed Constrained Shortest Path First (CSPF), color-based SR policies with Classful Transport resolution, backup paths with Topology-Independent Loop-Free Alternate (TI-LFA), and multitopology designs with Flex Algo.

This course also features a number of self-study modules, including a deeper dive into TI-LFA label stacks, and five modules on SRv6, including coverage on classic SRv6 SIDs and micro SIDs. This course is based on Junos OS Release 23.4R1.10. This course is also available On-Demand.
