Thanks, Alvaro.

A full diff vs. RFC 5880 can be seen via this URL:

https://author-tools.ietf.org/diff?url_1=https://www.rfc-editor.org/rfc/rfc5880.txt&url_2=https://www.ietf.org/archive/id/draft-ietf-bfd-rfc5880bis-01.txt&iddiff=1

One thing I'd like to suggest for the working group to think about for 
the bis to our base RFC 5880 is "meticulous" keying.  We found when we 
were working on the cluster of recent BFD authentication features, 
"meticulous" was defined in a way that generated significant IESG 
discussion.  The eventual resolution for this was the definition here:

https://datatracker.ietf.org/doc/html/draft-ietf-bfd-secure-sequence-numbers-27#name-meticulous-keying

"In this context, the term "meticulous" means that the Sequence number 
is incremented on every new packet which is sent.*"*
