Donatas,

I think the name "version" is too close to the BGP version that peers negotiate.

Why not use "debugging capability"?

Linda,

Per RFC4271:
A NOTIFICATION message is sent when an error condition is detected. The BGP connection is closed immediately after it is sent.

This is a general statement. You can't take it out of the current context.


Do most deployed implementations send "Subsequent OPEN" as you stated?
"Subsequent open would be tried without this new optional parameter"


Again we are discussing the addition of a new extension. Such addition can define in itself what implementation should do when receiving such a NOTIFICATION message indicating that peer does not understand the new extension.

Rgs,
R.
