Explains how TI-LFA protects SRv6 traffic during link or node failures and guides users through selecting, configuring, and verifying fast reroute protection.
This chapter details Topology Independent Loop-Free Alternate (TI-LFA) for SRv6, a mechanism ensuring rapid network recovery and service continuity.
Topology-Independent Loop-Free Alternates for SRv6
Explains how TI-LFA precalculates loop-free backup paths to protect SRv6 traffic against link, node, and SRLG failures and provide rapid forwarding recovery.
Usage Guidelines for SRv6 Ti-LFA
Describes the protection behavior, excluded resources, and path-selection priorities that users must consider when deploying link, node, or SRLG protection.
How SRv6 TI-LFA works
Describes how a PLR activates a precalculated backup path after detecting a failure and maintains connectivity while the IGP converges on a new primary path.
Configure TI-LFA
Guides users through configuring and verifying link, node, and SRLG protection with IS-IS and Flex-Algo in an SRv6 network.
