Dear WG Chairs, et. al, I cannot support WG LC for draft-ietf-bfd-optimizing-authentication as my comments at BFD WG meeting dating back to IETF-98 <https://datatracker.ietf.org/meeting/98/materials/minutes-98-bfd-00> still not have been addressed nor even there was an attempt to address. As I've asked to clarify impact of the proposed mechanism, particularly periodic authentication, on the BFD State Machine, I'd point that the proposed mechanism directly affects BFD security as discussed in RFC 5880 and the section Security Considerations in the document, in my view, does not adequately reflects that and doesn't explain how the security of the BFD session maintained when the periodic authentication is in use.
