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.
Conventions used in this document

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].
