Thanks!

It's not BGP protocol version, it's daemon/firmware version. So in

Yes, I can see value. However sometimes the BGP session is older than the
software release. There are implementations where the daemon is updated but
the BGP session stays up.

Perhaps exchanging the version - only - when the session is brought up
isn’t sufficient, and moving this into a message type of sorts may make
more sense.

Thoughts?

Kind regards,
