An introduction to Segment Routing and its concepts.
Learn about the foundational SR concepts.
See how segment routing leverages the existing MPLS data plane and learn how to verify segment routing MPLS forwarding.
See what the Segment Routing Global Block is. Learn about the best practices to use the same SRGB on all segment routing nodes. Further, learn how to modify the Segment Routing Global Block.
The SR IGP control plane and automated fast-reroute resiliency.
Learn how to use IS-IS or OSPF to distribute segments, how to configure segment routing and how segment routing works in a multi-area or multi-level network. Further, learn how to verify segment routing advertisements.
An introduction to the Topology Independent LFA technology. See how Topology Independent LFA provides a simple, automatic, optimal and topology independent sub-50ms per-prefix protection to the network. Further, see how TI-LFA protects Segment Routing, LDP and eventually IP traffic. In the end, learn how to verify TI-LFA using some examples.
SR and LDP
Introducing SR in an LDP network, how they can co-exist and interwork.
See how segment routing can co-exist with LDP and other MPLS protocols, both on the control plane and on the data plane. Further learn how to affect a simple migration from LDP to segment routing.
Learn about the objective of the Mapping Server and see how one may configure it. Further, verify the mapping server functionality.
Learn about the simple, automatic and seamless interworking between segment routing and LDP. See what the role of the Mapping Server is in the interworking functionality and learn about the interworking functionality on the data plane. Further verify the interworking forwarding entries.
SR Traffic Engineering
SR-TE provides you low-delay paths, disjoint paths,… and many more.
An introduction to the Segment Routing Traffic Engineering (SR-TE) technology. See how SR-TE provides a simple, automated, and scalable architecture to engineer traffic flows in a network. Further, see how the IOS XR based SR Path Computation Element (SR PCE) fits into this architecture.
Flexible Algorithm enriches the SR TE solution by adding additional segments having different properties than the IGP Prefix segments. Flex Algo adds flexible, user-defined segments to the SRTE toolbox. Flex Alg leverages SR on-demand next hop (ODN) and Automated Steering for intent-based instantiation of traffic engineered paths.
Apply the SR concepts to the IPv6 data plane and discover the power of SRv6 network programming.
An introduction to the SRv6 (Segment Routing over IPv6 dataplane) technology. Learn about the power of SRv6 network programming concept. Find out how SRv6 provides the ability to code directly into each packet header where the traffic should be sent and how the traffic should be treated. See how SRv6 makes your applications and your network inte...
SR Operations and Monitoring
Tools to monitor and operate your SR network.
The Delay Measurement solution, as part of the Performance Monitoring functionality, provides the dynamic measurement of link delays, which can then be distributed in IGP, BGP-LS and/or telemetry, to be used in SRTE path computation.
