Segment Routing Point-to-Multipoint Policy
RFC 9960, “Segment Routing Point-to-Multipoint Policy”, is a Proposed Standard document published in April 2026 by R. Parekh, D. Voyer, C. Filsfils, H. Bidgoli, Z. Zhang. It updates RFC 9524. The canonical text is published by the RFC Editor.
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
