Draft of message to be sent after approval:
From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: RFC Editor <email@example.com>, mpls mailing list <firstname.lastname@example.org>, mpls chair <email@example.com> Subject: Protocol Action: 'Label Advertisement Discipline for LDP FECs' to Proposed Standard (draft-ietf-mpls-ldp-applicability-label-adv-03.txt) The IESG has approved the following document: - 'Label Advertisement Discipline for LDP FECs' (draft-ietf-mpls-ldp-applicability-label-adv-03.txt) as Proposed Standard This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Adrian Farrel and Alia Atlas. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mpls-ldp-applicability-label-adv/
Technical Summary The label advertising behavior of an LDP speaker for a given FEC is governed by the FEC type and not necessarily by the LDP session's negotiated label advertisement mode. This document updates RFC 5036 to make that fact clear, as well as updates RFC 3212, RFC 4447, RFC 5918, RFC 6388, and RFC 7140 by specifying the label advertisement mode for all currently defined LDP FEC types. Working Group Summary There is a strong support for this document in the working group and it has been has been well reviewed. After AD review, the document was sent back to the WG for a substantial rewrite. A subsequent last call in the WG established support for the new revision. The document also got cleaned up during discussions with IANA in IETF last call (and that uncovered some bugs in the registry which was a whole lot of fun!). Document Quality The document describes what is effectively deployed implementation behaviour. Any disagreements with this would have resulted in loud shouts during WG last call. Any divergence from this presumably led to embarrassed silence during which code was frantically fixed. Personnel Loa Andersson (firstname.lastname@example.org) is the document shepherd. Adrian Farrel (Adrian@olddog.co.uk) is the responsible AD. RFC Editor Note Please use the expansion "Forwarding Equivalence Class" for FEC in the Abstract and on its first use. Section 4 Please remove the following bullet: - For the existing FEC types, populate this column with the values listed under section 2.2. IANA Note IANA, please note the RFC Editor Note applying to the IANA Considerations section.
