The chapters in this book guide you from basic concepts to advanced implementations, ensuring a logical progression of information. A recap of MPLS is followed by an in-depth exploration of SR, detailed configurations, migration strategies, service assurance, and high availability. The final chapters provide a glimpse into the future of SRv6 in data centers and cloud environments, explore business opportunities that justify investment in this new technology, and offer non-technical thoughts to streamline the transition to SR. This book is broken into 12 chapters and an appendix: Chapter 1, “MPLS in a Nutshell”: This chapter provides an introduction to MPLS technology and its significance in modern networking as well as an overview of MPLS mechanisms and benefits. Chapter 2, “What Is Segment Routing over MPLS (SR-MPLS)?”: This chapter provides a basic introduction to the general concepts of segment routing (SR) and explores SR-MPLS in the control plane and data plane. Chapter 3, “What Is Segment Routing over IPv6 (SRv6)?”: This chapter explores SRv6 in the control plane and data plane and provides an overview of the evolution and simplification of SR-driven networks. Chapter 4, “Segment Routing in Detail”: This chapter includes detailed information on configuration and verification of SR on Cisco devices and describes design guidelines and advanced features for SR networks. Chapter 5, “Migrating to Segment Routing”: This chapter is a practical roadmap for migrating from MPLS to SR and presents strategies for greenfield and brownfield deployments. Chapter 6, “L2VPN Service Deployment: Configuration and Verification Techniques”: This chapter provides an overview of customer-related L2VPN services implemented on an SRv6 underlay network. It includes basic configuration methodologies and service verifications. Chapter 7, “L3VPN Service Deployment: Configuration and Verification Techniques”: This chapter provides an overview of customer-related L3VPN services implemented on SRv6 and SR-MPLS underlay networks. It includes basic configuration methodologies and service verifications. Chapter 8, “Service Assurance”: This chapter presents procedures and processes for improving customer experience and satisfaction. It includes a discussion of tools and protocols for SLA monitoring and fault management in the transport network layer, as well as in the L2VPN and L3VPN service overlays. Chapter 9, “High Availability and Fast Convergence”: This chapter introduces technologies and features for high availability and fast convergence in SR networks. It includes a detailed discussion of failure detection, path computation, and network convergence. Chapter 10, “Business Opportunities”: This chapter describes the benefits of investing in SR and why network service providers should transition to this technology. It offers insights into how SRv6 can offer substantial opportunities and advantages over SR-MPLS as well as business case calculation guidance. Chapter 11, “Organizational Considerations”: This chapter examines the impact of SR on organizational structures and processes and provides a guide to managing the transformation to a programmable SR network. Chapter 12, “SRv6 Ecosystem Deployment Use Cases”: This online only chapter discusses the potential of SRv6 in data centers and cloud environments. It provides examples and interoperability scenarios involving open-source software. Appendix A, “Reference Diagrams and Information”: This appendix describes the reference diagrams and information of the SR-MPLS, SRv6, and SR migration network topologies used throughout the book in a single location for the reader’s convenience.
