Abstract

[RFC6826] describes how to map Point-to-Multipoint Label Switched Paths (P2MP LSPs) created by mLDP [RFC6388] to multicast trees created by Protocol Independent Multicast - Sparse Mode (PIM-SM) in Source-Specific Multicast (SSM) mode [RFC4607]. This document describes how to map mLDP P2MP trees to multicast trees created by PIM-SM in Any-Source Multicast (ASM) mode. It describes two possible mechanisms for doing this.

      Carrying Protocol Independent Multicast - Sparse Mode (PIM-SM)   in Any-Source Multicast (ASM) Mode Trees over Multipoint LDP (mLDP)

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).
