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)? --On Donnerstag, 19.
