Abstract

   This document documents the consensus reached by the Multiprotocol
   Label Switching (MPLS) Working Group within the IETF to focus its
   efforts on "Resource Reservation Protocol (RSVP)-TE: Extensions to
   RSVP for Label-Switched Paths (LSP) Tunnels" (RFC 3209) as the MPLS
   signalling protocol for traffic engineering applications and to
   undertake no new efforts relating to "Constraint-Based LSP Setup
   using Label Distribution Protocol (LDP)" (RFC 3212).  The
   recommendations of section 6 have been accepted by the IESG.

1. Introduction

1.1  Objectives of document

   This document documents the MPLS Working group consensus to continue
   to develop RFC 3209 [RFC3209] as the signalling protocol for MPLS
   signaling for Traffic Engineering applications.

   This document also documents the MPLS working group consensus to not
   undertake any new work related to RFC 3212 [RFC3212], e.g., there are
   no plans to progress RFC 3212 beyond proposed standard.  No other
   actions are taken relative the document status of RFC 3212 [RFC3212]
   or RFCs that specify extensions to RFC 3212.

   Section 6 summarizes the consensus of the MPLS working group on this
   issue.  This consensus has been accepted by the IESG.  All other
   sections are documentation of the consensus process.

1.2 Nomenclature

   This document uses the term "CR-LDP related working group drafts" to
   refer to a group of Internet Drafts that specify changes or
   extensions to [RFC3212] and the term "CR-LDP related RFCs" to discuss
   the group of RFCs that specify the protocol and the applicability of
   [RFC3212].
