Purpose: For information

Body: The BBF thanks the IETF BFD WG for informing us of important work on the BFD Echo.

We wanted to clarify the "overlapping use case with TR-146". TR-146 leverages BFD Echo as a connectivity check mechanism. It does so in a manner where the peer does not need a full BFD implementation to echo the packet received. In our opinion, no future standardization is required to support TR-146. There is no current interest in revising TR-146 to leverage the enhancement of the BFD protocol.
We noted in the BBF community that those interested in participating should do so in the IETF BFD WG.
 
Sincerely,
 
Lincoln Lavoie,
Broadband Forum Technical Committee Chair
