Internet-Draft draft-ietf-spring-segment-protection-sr-te-paths-06.txt is now available. It is a work item of the Source Packet Routing in Networking (SPRING) WG of the IETF. Title: Segment Protection for SR-TE Paths Authors: Shraddha Hegde Chris Bowers Stephane Litkowski Xiaohu Xu Feng Xu Name: draft-ietf-spring-segment-protection-sr-te-paths-06.txt Pages: 20 Dates: 2024-02-09 Abstract: Segment routing supports the creation of explicit paths using Adj- Segment-ID (SID), Node-SIDs, and BSIDs. It is important to provide fast reroute (FRR) mechanisms to respond to failures of links and nodes in the Segment-Routed Traffic-Engineered(SR-TE) path. A point of local repair (PLR) can provide FRR protection against the failure of a link in an SR-TE path by examining only the first (top) label in the SR label stack. In order to protect against the failure of a node, a PLR may need to examine the second label in the stack as well, in order to determine SR-TE path beyond the failed node. This document specifies how a PLR can use the first and second label in the SR-MPLS label stack describing an SR-TE path to provide protection against node failures.
