Internet-Draft draft-ietf-rtgwg-segment-routing-ti-lfa-12.txt is now available. It is a work item of the Routing Area Working Group (RTGWG) WG of the IETF. Title: Topology Independent Fast Reroute using Segment Routing Authors: Stephane Litkowski Ahmed Bashandy Clarence Filsfils Pierre Francois Bruno Decraene Daniel Voyer Name: draft-ietf-rtgwg-segment-routing-ti-lfa-12.txt Pages: 26 Dates: 2023-11-17 Abstract: This document presents Topology Independent Loop-free Alternate Fast Re-route (TI-LFA), aimed at providing protection of node and adjacency segments within the Segment Routing (SR) framework. This Fast Re-route (FRR) behavior builds on proven IP-FRR concepts being LFAs, remote LFAs (RLFA), and remote LFAs with directed forwarding (DLFA). It extends these concepts to provide guaranteed coverage in any two connected networks using a link-state IGP. A key aspect of TI-LFA is the FRR path selection approach establishing protection over the expected post-convergence paths from the point of local repair, reducing the operational need to control the tie-breaks among various FRR options.
