Abstract:

   This document presents Topology Independent Loop-free Alternate Fast
   Reroute (TI-LFA), aimed at providing protection of node and adjacency
   segments within the Segment Routing (SR) framework.  This Fast
   Reroute (FRR) behavior builds on proven IP Fast Reroute 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.  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, reducing the operational need to control
   the tie-breaks among various FRR options.
