The IESG has approved the following document: - 'GMPLS RSVP-TE Extensions for Lock Instruct and Loopback' (draft-ietf-teas-rsvp-te-li-lb-05.txt) as Proposed Standard This document is the product of the Traffic Engineering Architecture and Signaling Working Group. The IESG contact persons are Alia Atlas and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-teas-rsvp-te-li-lb/ Technical Summary This document specifies extensions to Resource Reservation Protocol- Traffic Engineering (RSVP-TE) to support Lock Instruct (LI) and Loopback (LB) mechanisms for Label Switched Paths (LSPs). These mechanisms are applicable to technologies which use Generalized Multi-Protocol Label Switching (GMPLS) for the control plane. Working Group Summary This document moved from the CCAMP to TEAS WGs as part of the routing WG changes. This document has been fairly noncontroversial. Document Quality The base GMPLS protocol has been implemented. The extensions defined in this document are compatible with earlier implementations and satisfy requirements previously documented in RFCs. While there have been no public statements on implementation, the authors are from multiple vendors and an operator, and implementation is expected. Personnel Lou Berger is the Document Shepherd Adrian Farrel is the Responsible Area Director RFC Editor Note s3.2, para 2: OLD: The ingress node MUST ensure that the entity (node or interface), at which loopback is intended to occur, is marked as a strict hop in the Explicit Route Object (ERO) subobject. NEW: The ingress node MUST ensure that the entity at which loopback is intended to occur is explicitly identified by the immediately preceding subobject of the ERO Hop Attributes subobject. END s3.2, para 3, AFTER Otherwise, the node SHOULD try to put the LSP into loopback mode. ADD The loopback SHOULD be enabled on the entity identified by the ERO subobject immediately prior to the ERO Hop Attributes subobject. If the immediately preceding subobject is a label subobject [RFC3473], the loopback SHOULD be enabled for the direction indicated by the U bit of the label subobject. END
