The IESG has approved the following document: - 'BFD For MPLS LSPs ' <draft-ietf-bfd-mpls-07.txt> as a Proposed Standard This document is the product of the Bidirectional Forwarding Detection Working Group. The IESG contact persons are Ross Callon and David Ward. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-bfd-mpls-07.txt Technical Summary One desirable application of Bi-directional Forwarding Detection (BFD) is to detect a MPLS LSP data plane failure. LSP-Ping is an existing mechanism for detecting MPLS data plane failures and for verifying the MPLS LSP data plane against the control plane. BFD can be used for the former, but not for the latter. However the control plane processing required for BFD control packets is relatively smaller than the processing required for LSP-Ping messages. A combination of LSP-Ping and BFD can be used to provide faster data plane failure detection and/or make it possible to provide such detection on a greater number of LSPs. This document describes the applicability of BFD in relation to LSP-Ping for this application. It also describes procedures for using BFD in this environment. Working Group Summary This working group has operated quite smoothly. Document Quality This use of BFD has been implemented and deployed by multiple vendors. Personnel Dave Ward is the Document Shepherd for this document. Ross Callon is the Responsible Area Director. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
