Hi Prasad,
thank you for leading this work. Could you please clarify one issue for me. Is this -01 version off the github? The github link from the datatracker brought me to the -00 version of the 5884bis draft.

Regards,
Greg

Hello BFD/ MPLS WG members,
Based on the discussions of the Vienna meeting, I have added contents to the document below. Please review the same and share comments/ suggestions. Implementation reports are welcome through email, so we can progress the draft to WGLC. I plan to add implementation reports in the next revision.
Thanks
Prasad

Internet-Draft draft-ietf-bfd-rfc5884-bis-01.txt is now available. It is a work item of the Bidirectional Forwarding Detection (BFD) WG of the IETF.

   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.
