Segment Routing and TI-LFA in MPLS Networks

Modern service provider and enterprise networks demand simplified control planes and rapid traffic restoration. Segment Routing (SR) revolutionizes MPLS networks by removing complex protocols like LDP and RSVP-TE, replacing them with efficient, source-based routing. This text-only course guides you from the foundational concepts of Segment Routing to understanding resilient path designs and advanced protection mechanisms. You will gain the knowledge needed to analyze, design, and troubleshoot SR-enabled MPLS architectures. What you will learn: Understand the foundational architecture of Segment Routing and how it simplifies the MPLS control plane; Configure Segment Routing global blocks, node segments, and adjacency segments; Implement TI-LFA (Topology-Independent Loop-Free Alternate) for sub-50ms traffic restoration; Analyze path computation element (PCE) architectures and traffic engineering policies; Explore modern evolution paths, including SRv6 and integration with EVPN. The course begins with core terminology and routing fundamentals before moving into detailed protocol extensions, traffic engineering, and fast-reroute mechanisms. You will study practical configuration scenarios and theoretical packet walks to solidify your understanding. This course is designed for network engineers, administrators, and students who have a basic understanding of IP routing and MPLS, with no prior experience in Segment Routing required.
