Technical Summary

   This document describes active tail extensions to and updates the
   Bidirectional Forwarding Detection (BFD) protocol for multipoint
   networks.

Working Group Summary

   The document was discussed multiple times with participation from multiple members of the BFD WG.
   The discussions on whether a separate draft (v/s move to appendix) was needed for active-tail went on for a while but consensus was reached.
   Most of the technical discussions took place in 2014/2015 when the active-tail functionality was still part of the multipoint draft (i.e. before the split).
   The technical discussions were mostly on the notification mechanisms to the head, whether they are all needed and how the operate.

Document Quality

   The document has been reviewed multiple times on the BFD WG mailing list. 
   There is no known implementation of this draft. 

Personnel

   Reshad Rahman is the document shepherd, BFD WG co-chair.
   Martin Vigoureux is the responsible AD.
