Thanks Guy, here we go:

115599 prefixes from SPRINT 117736 prefixes from GEANT 2137 difference (~5%)

I can't believe that those 5% are making 380 update messages per minute !? But of course this might be one part of the +update messages.

Seems unlikely. But, if the 80/20 rule applies (80% of activity is created by 20% of the prefixes), then you'd expect 20000 prefixes to generate around that many announces/withdraws. BTW, 2.1k is about 2% of 110k ;-) This adds weight to your argument rather than diminishing it... Regards, Guy This e-mail is private and may be confidential and is for the intended recipient only.
