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. 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.
