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 network 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.
