This document describes extensions to the Label Distribution Protocol (LDP) for the setup of point to multi-point (P2MP) and multipoint-to- multipoint (MP2MP) Label Switched Paths (LSPs) in Multi-Protocol Label Switching (MPLS) networks. The solution relies on LDP without requiring a multicast routing protocol in the network. Protocol elements and procedures for this solution are described for building such LSPs in a receiver-initiated manner. There can be various applications for P2MP/MP2MP LSPs, for example IP multicast or support for multicast in BGP/MPLS L3VPNs. Specification of how such applications can use a LDP signaled P2MP/MP2MP LSP is outside the scope of this document.
