Internet Engineering Task Force (IETF) J. Le Roux, Ed. Request for Comments: 6348 T. Morin, Ed. Category: Historic France Telecom - Orange ISSN: 2070-1721 September 2011 Requirements for Point-to-Multipoint Extensions to the Label Distribution Protocol Abstract This document lists a set of functional requirements that served as input to the design of 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 Multiprotocol Label Switching (MPLS) infrastructure. This work was overtaken by the protocol solution developed by the MPLS working group, but that solution did not closely follow the requirements documented here. This document is published as a historic record of the ideas and requirements that shaped the protocol work. Status of This Memo This document is not an Internet Standards Track specification; it is published for the historical record. This document defines a Historic Document for the Internet community. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Not all documents approved by the IESG are a candidate for any level of Internet Standard; see Section 2 of RFC 5741.
