The IESG has received a request from the Routing Area Working Group WG
(rtgwg) to consider the following document: - 'Topology Independent Fast
Reroute using Segment Routing'
  <draft-ietf-rtgwg-segment-routing-ti-lfa-13.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2024-03-05. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

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.
