Abstract

This document describes extensions to the Label Distribution Protocol (LDP)for the setup of point-to-multipoint (P2MP) and multipoint-to-multipoint(MP2MP) Label Switched Paths (LSPs) in MPLS networks.These extensions are also referred to as multipoint LDP. MultipointLDP constructs the P2MP or MP2MP LSPs withoutinteracting with or relying upon any other multicast treeconstruction protocol. Protocol elements and procedures for thissolution are described for building such LSPs in areceiver-initiated manner. There can be various applications formultipoint LSPs, for example IP multicast or supportfor multicast in BGP/MPLS Layer 3 Virtual Private Networks (L3VPNs).Specification of how such applications can use an LDP signaled multipoint LSP is outside the scope of this document.
