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.
