RFC 9960 - Segment Routing Point-to-Multipoint Policy

  • Status: Proposed Standard
  • Published: April 2026
  • Stream: IETF
  • Updates: RFC9524
  • Errata: No Errata

Abstract​

The Point-to-Multipoint (P2MP) Policy enables creation of P2MP trees for efficient multipoint packet delivery in a Segment Routing (SR) domain. This document specifies the architecture, signaling, and procedures for SR P2MP Policies with Segment Routing over MPLS (SR-MPLS) and Segment Routing over IPv6 (SRv6). It defines the SR P2MP Policy construct, candidate paths (CPs) of an SR P2MP Policy, and the instantiation of the P2MP tree instances (PTIs) of a CP using Replication segments. Additionally, it describes the required extensions for a controller to support P2MP path computation and provisioning. This document updates RFC 9524.
