Junos Segment Routing with SRv6 Micro-SIDs

This three-day, advanced-level course provides an in-depth introduction to segment routing (SR), otherwise known as Source Packet Routing in Networking (SPRING). The course focuses on using IS-IS and BGP to deploy Segment Routing for IPv6 (SRv6) micro-SIDs, which encode multiple instructions into a single IPv6 address in the data plane.
After exploring the features and use cases for SRv6 with micro-SIDs, students are introduced to the fundamentals of a segment-routed network, such as locator blocks, locator prefixes, and a variety of BGP service functions such as uDT4 and uDT6 segments. This also includes VPN configuration, with a focus on Layer 3 VPNs and the MPLS label transposition process.
Students are then taught how an SRv6 micro-SID network can encode multiple segments into a single address, and the segment popping process that takes place across a path. Students configure End and End.X transport segments to test this, which acts as a starting point to deploy a variety of backup paths with Topology-Independent Loop-Free Alternate (TI-LFA). A self-study section then follows that considers topics including classic SRv6, microloop avoidance, and the three flavor behaviors of SRv6 transport segments.
Students also briefly learn the most fundamental concepts of Segment Routing for MPLS (SR-MPLS). This knowledge enables students to compare and contrast the two SR methods.
This course is based on Junos OS Release 25.2R1.8.
