Key Features

Carry out practical labs to thoroughly grasp and execute MPLS, SR-MPLS, and FRR techniques Master SR-MPLS and LDP interoperability for seamless integration and efficient network operation Implement TI-LFA FRR methods for seamless SR-MPLS deployment in production Purchase of the print or Kindle book includes a free PDF eBook

Book DescriptionIn this book, you will learn about segment routing (SR), a cornerstone of modern networking, and topology-independent loop-free alternate (TI-LFA), with hands-on labs to hit the ground running. Written by a key contributor to global segment routing multiprotocol label switching (SR-MPLS) network designs, this book makes learning SR-MPLS both accessible and insightful. The book offers an extensive learning path, taking you from a traditional MPLS network using the label distribution protocol (LDP) to a modern SR-MPLS network using SR, and provides a holistic view of their interworking. You’ll also explore TI-LFA fast reroute protection scenarios, and find out how SR-MPLS strengthens network reliability with its source routing paradigm. Using intermediate system–to–intermediate system (IS-IS) as the foundational link-state routing protocol, the chapters ensure that you get a clear understanding of both SR and IS-IS. Following a consistent network topology throughout, this book enables smooth transitions between scenarios, helping you master the technical concepts without distraction. By the end of this book, you’ll have a solid grasp of MPLS, SR-MPLS, and TI-LFA fast reroute techniques, ready to tackle real-world networking challenges with confidence. What you will learn

Gain a complete understanding of MPLS and its role in network infrastructures Develop practical skills to implement SR-MPLS using Cisco IOS-XRv9k and real-life use cases Acquire hands-on experience with MPLS networks using the IS-IS and LDP protocols Orchestrate the gradual transition from traditional MPLS to SR-MPLS networks and manage their interworking Master fast reroute techniques in SR-MPLS networks, including TI-LFA, for efficient traffic rerouting Implement path protection methods to ensure network resilience and stability

Who this book is forThis book is for MPLS professionals and network engineers looking to deepen their knowledge in SR and TI-LFA. A basic understanding of MPLS networks is a prerequisite, but worry not—the book also covers foundational MPLS concepts, ensuring network enthusiasts can follow along without any problem. This book is specifically designed for network engineering, operations, and design professionals, covering advanced techniques such as TI-LFA for path protection, empowering you to evolve MPLS networks with SR-MPLS seamlessly.
