Ballot Text
Technical Summary
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.
Working Group Summary
It is strongly advocated by a few, but most are relatively silent. However, this is a widely implemented protocol with no WG objection for publication.
Document Quality
Widely implemented and deployed protocol.
Personnel
The Document Shepherd for this document is Stewart Bryant. The
Responsible Area Director is Jim Guichard.
