Carrying Protocol Independent Multicast - Sparse Mode in Any-Source Multicast Mode Trees over Multipoint LDP
RFC 7442, “Carrying Protocol Independent Multicast - Sparse Mode in Any-Source Multicast Mode Trees over Multipoint LDP”, is a Proposed Standard document published in February 2015 by Y. Rekhter, R. Aggarwal, N. Leymann, W. Henderickx, Q. Zhao, R. Li. The canonical text is published by the RFC Editor.
Abstract
When IP multicast trees created by Protocol Independent Multicast - Sparse Mode (PIM-SM) in Any-Source Multicast (ASM) mode need to pass through an MPLS domain, it may be desirable to map such trees to Point-to-Multipoint Label Switched Paths (P2MP LSPs). This document describes how to accomplish this in the case where such P2MP LSPs are established using Label Distribution Protocol (LDP) Extensions for P2MP and Multipoint-to-Multipoint LSPs: Multipoint LDP (mLDP).
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.
