Segment Routing in MPLS Networks: Transition from traditional MPLS to SR-MPLS with TI-LFA FRR

From CyberSecurity Summary CyberSecurity Summary

A comprehensive guide for network professionals transitioning from traditional Multiprotocol Label Switching (MPLS) to Segment Routing MPLS (SR-MPLS). It aims to simplify this complex shift through theoretical explanations and practical lab exercises, using network emulators like EVE-NG and virtual Cisco XRv9k routers. The text explores fundamental concepts such as IP addressing, Interior Gateway Protocols (IGP) like IS-IS, Label Distribution Protocol (LDP), and various aspects of Fast Reroute (FRR) in SR-MPLS networks, including Topology Independent – Loop-Free Alternate (TI-LFA) and microloop avoidance. Additionally, the book covers SR-LDP interworking, demonstrating how different MPLS domains can seamlessly connect, making it a valuable resource for hands-on learning and reinforcing networking expertise.
