Hi Gyan,
thank you for your interest in this draft. We've described how RFC 8562 BFD
for Multipoint Networks <https://datatracker.ietf.org/doc/rfc8562/> can be
used to shorten convergence in PIM-SM. The similar scenario discussed in
draft-ietf-bess-mvpn-fast-failover
<https://datatracker.ietf.org/doc/draft-ietf-bess-mvpn-fast-failover/> where
p2mp BFD is used by tails to detect the failure of the head/root or the
multicast tree. If it is required for the head/root to detect a defect of
the multicast tree toward a tail, we'll turn to RFC 8563 BFD for
Multipoint  Active Tails <https://datatracker.ietf.org/doc/rfc8563/> as in
draft-hu-bier-bfd <https://datatracker.ietf.org/doc/draft-hu-bier-bfd/>.
Hope this information would be helpful to you. I always welcome your
questions.

Regards,
Greg
