Abstract

This document specifies the IGP protocol extensions required to support SRv6 path egress protection using the Mirror SID (End.M) mechanism. It reuses the existing SRv6 End SID sub-TLV defined in RFC 9352 (IS-IS, Section 7.2) and RFC 9513 (OSPFv3, Section 8) with the End.M endpoint behavior (74) to advertise the Mirror SID and the set of protected locators, and defines a new Protected Locators sub-(sub-)TLV. enabling a backup egress node (protector) to signal its capability to protect a primary egress node within a single link- state IGP area. This document is a companion to [I-D.ietf-rtgwg-srv6-egress-protection], which specifies the overall SRv6 path egress protection mechanism and the End.M behavior. The IGP encoding defined herein provides the signaling substrate for that mechanism.
