As a followup to mic comment on Friday afternoon of IETF 95, we should consider an explicit code point for "empty/null" authentication. This covers the cases where authentication fields in protocols need to be used, but no mechanism providing authentication is in use.
BFD, however, has an unusual form of this case: 1. We support the *absence* of authentication. 2. We have work to add an explicit authentication code point with no authentication, simply to take advantage of some sequencing numbers in the authentication field. -- Jeff _______________________________________________ rtgwg mailing list [email protected] https://www.ietf.org/mailman/listinfo/rtgwg
