Dear All,
in the new section, Operational Considerations
<https://tools.ietf.org/html/draft-ietf-mpls-bfd-directed-12#section-5>;,
we've described the use of LSP Ping with BFD Reverse Path TLV is described
for scenarios of planned and unexpected changes of the FEC to which the
reverse direction of a BFD session is tied. We believe that with this
update all outstanding technical comments have been addressed.

Regards,
Geg
