Segment Routing Guide
Overview
The OcNOS Segment Routing Guide provides a unified reference for Segment Routing features and capabilities supported in OcNOS. Segment Routing (SR) simplifies traffic steering and network programmability by encoding path information directly into packet headers and eliminating dependency on additional protocols like RSVP-TE. The guide covers SR using MPLS data planes, explains SR integration with IGPs (IS-IS/OSPF), and describes policy-based traffic engineering and fast reroute mechanisms.
This guide explains SR concepts, deployment models, and operational behavior with configuration examples, command references, and best-practice guidance. It helps users understand how OcNOS Segment Routing operates and how to plan, configure, and verify SR deployments in service provider and enterprise environments.
Target Users
This guide is intended for:
• Network architects designing scalable and programmable traffic steering solutions.
• Operations teams deploying and maintaining Segment Routing domains.
• Support engineers troubleshooting SR control-plane and forwarding behavior.
• Technical planners evaluating SR capabilities and design options.
Key Capabilities
This guide enables users to:
• Understand Segment Routing fundamentals, including MPLS data planes.
• Configure Segment Routing with IGPs (IS-IS/OSPF) and centralized policies.
• Explore SR traffic engineering with policies, colors, and constraints.
• Deploy fast reroute mechanisms for enhanced convergence and resilience.
• Integrate SR with MPLS-based services and VRFs.
• Use detailed examples and CLI references for SR configuration and verification.
