The IESG has approved the following document: - 'Segment Routing Point-to-Multipoint Policy' (draft-ietf-pim-sr-p2mp-policy-22.txt) as Proposed Standard
This document is the product of the Protocols for IP Multicast Working Group. The IESG contact persons are Gunter Van de Velde, Jim Guichard and Ketan Talaulikar. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-pim-sr-p2mp-policy/ Technical Summary Point-to-Multipoint (P2MP) policy enables creation of P2MP trees for efficient multi-point packet delivery in a Segment Routing (SR) domain. A SR P2MP Policy consists of Candidate Paths (CP) which define the topology of P2MP tree instances in each Candidate Path. A P2MP tree instance is instantiated by a set of Replication segments. This document specifies the architecture, signaling, and procedures for SR P2MP Policies within Segment Routing over MPLS (SR-MPLS) and Segment Routing over IPv6 (SRv6) dataplane. It defines the P2MP Policy construct, the roles of the root and leaf nodes, Candidate Paths and and how P2MP trees using Replication Segments are instantiated and maintained. Additionally, it describes the required extensions for Path Computation Element (PCE) to support P2MP path computation and provisioning. Working Group Summary Was there anything in the WG process that is worth noting? For example, was there controversy about particular points or were there decisions where the consensus was particularly rough? No specific difficult issues observed Document Quality Are there existing implementations of the protocol? Have a significant number of vendors indicated their plan to implement the specification? Are there any reviewers that merit special mention as having done a thorough review, e.g., one that resulted in important changes or a conclusion that the document had no substantive issues? If there was a MIB Doctor, Media Type, or other Expert Review, what was its course (briefly)? In the case of a Media Type Review, on what date was the request posted? There is a implementation. Personnel The Document Shepherd for this document is Mike McBride. The Responsible Area Director is Gunter Van de Velde.
