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. Regards CP

It could also be due to the fact that SPRINT certainly constrains (or used to constrain) the maximum prefix length it will accept (not longer than /24 - used to be /18 I think but that was way too restrictive). Don't know about GEANT? Logically, you'd expect smaller blocks to be flapped more than larger aggregates so removing the smaller blocks entirely from what you accept/announce would reduce the number of announcements/withdrawls you make (even taking flap damping into account). It might be worth looking at the relative size of the "full" routing tables you receive from SPRINT and GEANT. If it's more from GEANT, that might be the answer.

RIPE NCC's DNS server available in IPv6
by Daniel Diaz 09 Dec '02

09 Dec '02

Dear all, We are glad to announce that since November 29, RIPE NCC's DNS service (ns.ripe.net) is also available in IPv6. This was an action on RIPE NCC for RIPE 43 and it is now accomplished. ns.ripe.net internet address = 193.0.0.193 ns.ripe.net IPv6 address = 2001:610:240:0:193::193 Best regards. -- Daniel.Diaz Operations Manager RIPE NCC

Hi around, can anyone of you point me to statistics about the frequency of BGP updates measured at some point in the internet? A customer complained about av. 10 updates per second which we consider normal, but we'd like to see values for comparison. Thanks Karsten
