    abstract =  {This document lists a set of functional requirements for Label Distribution Protocol (LDP) extensions for setting up point-to- multipoint (P2MP) Label Switched Paths (LSP), in order to deliver point-to-multipoint applications over a Multi Protocol Label Switching (MPLS) infrastructure. It is intended that solutions that specify LDP procedures for setting up P2MP LSP satisfy these requirements.},
