ISPs?

[Christian Meutes]

I am also very interested in pps with IMIX type of traffic you are having.
How does FreeBSD with $preferred_BGP_daemon scales on IX with dozens or 
hundred
of peers and having two or more full feeds?

How fast is the convergence in IGP/BGP? And how do you guys do 
configuration changes
without interrupting everything (reloading daemon)?
