LDP Specification
RFC 5036, “LDP Specification”, is a Draft Standard document published in October 2007 by L. Andersson, I. Minei, B. Thomas. It obsoletes RFC 3036. It has since been updated by RFC 6720, RFC 6790, RFC 7358, RFC 7552. The canonical text is published by the RFC Editor.
Abstract
The architecture for Multiprotocol Label Switching (MPLS) is described in RFC 3031. A fundamental concept in MPLS is that two Label Switching Routers (LSRs) must agree on the meaning of the labels used to forward traffic between and through them. This common understanding is achieved by using a set of procedures, called a label distribution protocol, by which one LSR informs another of label bindings it has made. This document defines a set of such procedures called LDP (for Label Distribution Protocol) by which LSRs distribute labels to support MPLS forwarding along normally routed paths. [STANDARDS-TRACK]
What “Draft Standard” means
A historical maturity level (retired in 2011) that sat between Proposed Standard and Internet Standard and required multiple interoperable implementations.
