[mpls] FW: New Version Notification for draft-ietf-bfd-rfc5884-bis-00.txt

["Vengada Prasad Govindan (venggovi)" <[e-mail]>]

Hello BFD/ MPLS WG,
As part of BFD RFCs being promoted to Internet Standard, please find the -00 version of the rfc5884-bis (the combined bis draft for RFC5884 and RFC7726). I have also incorporated 3 known errata for RFC5884 that have already been published. This document is the union of two RFCs (RFC5884 contributing most of the text). It requires a good review from the WG for the flow of the document since two documents got merged. There is a questionnaire to be filled by implementors in the Appendix. If you have experience with implementations/ deployments, please respond to the questionnaire (I will be happy to record your responses in the document if you respond to me over email copying the WG as well).

Thanks
Prasad

Title:    Bidirectional Forwarding Detection (BFD) for MPLS Label Switched Paths (LSPs)

Abstract:

   One desirable application of Bidirectional Forwarding Detection (BFD)
   is to detect a Multiprotocol Label Switching (MPLS) Label Switched
   Path (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.  This document
   obsoletes RFC5884 and RFC7726.
