Hi Gyan,
BFD strict mode below specifies how OSPF signals its requirement for BFD to be
up. If you have OSPF at each end, no need for "unsolicited BFD".

Hi Reshad
Also I think unsolicited BFD should apply as well to BFD strict mode.
https://datatracker.ietf.org/doc/html/draft-ietf-lsr-ospf-bfd-strict-mode
I will comment on that thread.
Kind Regards

Hi Reshad
Could this unsolicited BFD concept be applied to S-BFD RFC 7880, 7881, 7885?
Also could it be applied to RFC 5880 demand mode?
I will review through the draft again for any further comments.
Many Thanks
Gyan

Hi Gyan,
Apologies for the delay and thanks for the feedback.
The document is applicable to single-hop and multi-hop. In the next revision,
we will clarify this and extend the YANG model to include multi-hop.
The "unsolicited BFD" procedure allows a BFD session to be initiated only by 1
side. Once that BFD session is up, demand mode may or may not kick in, just
like for RFC5880 BFD. So unsolicited BFD and demand mode are orthogonal.
The procedures in this document apply to RFC5880, aka classical, BFD. S-BFD
session bringup is different, requires sharing S-BFD discriminators etc (as
mentioned in the Introduction).
Wrt which RFCs are updated by this document: we need to add 9127 (or 9127-bis).
Regards,Reshad.

Dear Authors
This is a very useful specification for operators.
Is this draft applicability for single hop, multi hop, demand and S-BFD
sessions.
Also what RFC’s does this draft update?
