Unlock the Future of Networking with Segment Routing: Your Comprehensive Guide to SR-MPLS and SRv6 for Service Provider and Enterprise Networks
In the ever-evolving landscape of networking, this book is your essential resource for mastering the cutting-edge technology of Segment Routing (SR). Authored by industry experts, this book offers a deep dive into the world of SR, from foundational principles to advanced implementations.
This guide begins with a brief recap of MPLS, setting the stage for an in-depth exploration of SR-MPLS and SRv6. Each chapter is meticulously crafted to provide a holistic understanding of SR, featuring practical examples and detailed configurations for both IOS-XR and IOS-XE platforms. Network engineers, architects, and operators will find invaluable insights and step-by-step instructions to effectively implement and manage SR technologies and overlay services.
Beyond the technical details, the book delves into the business and organizationalimplications of adopting SR. Learn how SR can drive growth, improve customer experience, and streamline operations. With sections on SRv6 deployments in data centers and cloud environments, including lab support materials, you'll be ready for the next wave of networking innovations.
Book features include:
Practical insights drawn from real-world deployments, including diagrams, design guidelines, configuration examples, packet captures, and troubleshooting tips
Logical progression from basic concepts to advanced implementations, suitable for both beginners and seasoned professionals
Extensive configuration and verification examples for overlay services like L2VPN (EVPN) and L3VPN
SRv6 open-source implementations for data centers and cloud environments
Business-oriented chapters outlining the benefits of SR
