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.
