A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Routing Area Working Group WG of the IETF. Title : Topology Independent Fast Reroute using Segment Routing Authors : Stephane Litkowski Ahmed Bashandy Clarence Filsfils Bruno Decraene Pierre Francois Daniel Voyer Francois Clad Pablo Camarillo Filename : draft-ietf-rtgwg-segment-routing-ti-lfa-01.txt Pages : 24 Date : 2019-03-05 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 IGP network. 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, dramatically reducing the operational need to control the tie-breaks among various FRR options.
