Topology Independent Fast Reroute Using Segment Routing
RFC 9855

Received changes through RFC Editor sync (created document RFC 9855, created became rfc relationship between draft-ietf-rtgwg-segment-routing-ti-lfa and RFC 9855, set title to 'Topology Independent Fast Reroute Using Segment Routing', set abstract to 'This document presents Topology Independent Loop-Free Alternate (TI-LFA) Fast Reroute (FRR), which is aimed at providing protection of node and Adjacency segments within the Segment Routing (SR) framework.  This FRR behavior builds on proven IP FRR concepts being LFAs, Remote LFAs (RLFAs), and Directed Loop-Free Alternates (DLFAs).  It extends these concepts to provide guaranteed coverage in any two-connected networks using a link-state IGP.  An important aspect of TI-LFA is the FRR path selection approach establishing protection over the expected post-convergence paths from the Point of Local Repair (PLR), reducing the operational need to control the tie-breaks among various FRR options.', set pages to 23, set standardization level to Proposed Standard, added RFC published event at 2025-10-28)
