COMMENT:
----------------------------------------------------------------------

Hi Ashesh, Mahesh, Ankur, Santosh, and Mach,

Thank you for the effort put into this document.

Thanks also to Gyan Mishra for the OPSDIR review and to Jeff for the follow-up.

Please find below some comments with a focus on the YANG part:

# YANG terminology

CURRENT:
   This YANG module imports Common YANG Types [RFC6991], A YANG Data
   Model for Routing [RFC8349], and YANG Data Model for Bidirectional
   Forwading Detection (BFD) [RFC9314].

This should reason about importing the various modules, not data models. Please
refer to 8407bis which says:

“Likewise, "YANG module" should be used when using terms related to YANG module
specifications (e.g., augmentation or deviation).“

# Consistency

Section 7.2 has:

CURRENT: prefix "bfds";

I suggest to be consistent with the pattern used so far for BFD (bfd-ip-mh,
bfd-ip-sh, bfd-lag, etc.).

NEW: prefix bfd-s;

# Description

Consider updating the description of the module to highlight this is about
experimental extensions.

# Feature Description

OLD:
       description
         "If supported, the feature allows for BFD sessions to be
          monitored for packets lost.";

NEW:
       description
         "Indicates that the implementation supports monitoring
          of packets lost in BFD sessions.";

# Modules live outside documents

OLD:
       description
         "BFD Null Auth type defined in this draft.";

NEW:
       description
         "BFD Null Auth type.";

# Security template

Please update 9.2 to follow the template in RFC8407bis.

# Normative references

RFC6241, RFC8040, RFC8446, 9000 should be listed as informative. Please refer
to the note at https://wiki.ietf.org/group/ops/yang-security-guidelines

Cheers,
Med
