The IESG has approved the following document: - 'Using the Generic Associated Channel Label for Pseudowire in MPLS-TP' (draft-ietf-pwe3-mpls-tp-gal-in-pw-01.txt) as a Proposed Standard This document is the product of the Pseudowire Emulation Edge to Edge Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-pwe3-mpls-tp-gal-in-pw/ Technical Summary This document describes the requirements for using the Generic Associated Channel Label (GAL) in Pseudowires (PWs) in MPLS-TP networks, and provides an update to the description of GAL usage in RFC5586 by removing the restriction that is imposed on using GAL for PWs especially in MPLS-TP environments. This is required to allow PWs that do not use a PW control word to be used in MPLS-TP and for them to use the full range of MPLS-TP OAM supported by the G-ACh. This document is a product of the PWE3 working group. This document is STANDARDS TRACK. Working Group Summary There is consensus in the working group for this change to RFC5586. Document Quality There are no concerns with document quality. Personnel Matthew Bocci (matthew.bocci@alcatel-lucent.com) is the Document Shepherd for this document. Stewart Bryant (stbryant@cisco.com) is the Responsible Area Director RFC Editor Note In abstract s/[RFC5586]/RFC5586/ Section 1 s/associated control channel/Associated Channel/ (per RFC 5085) s/generalizes this for use in the/generalizes this for use as the/ s/but places restrictions on GAL usage with PWs. /but prohibits GAL usage with PWs./ In section 3 OLD [RFC3985] architectures appropriate NEW [RFC3985] architectures as appropriate END s/but not for PWs using an MPLS-TP PSN./ but not for PWs in an MPLS-TP network./ ... and at the very bottom of section 3 OLD is replaced by: In MPLS-TP, the GAL MUST be used with packets on a G-ACh on LSPs, Concatenated Segments of LSPs, and with Sections, and MAY be used with PWs. It MUST always be at the bottom of the label stack (i.e., S bit set to 1). However, in other MPLS environments, this document places no restrictions on where the GAL may appear within the label stack. NEW is replaced by: In MPLS-TP, the GAL MUST be used with packets on a G-ACh on LSPs, Concatenated Segments of LSPs, and with Sections, and MAY be used with PWs. The presence of a GAL indicates that an ACH immediately follows the MPLS label stack.
