ok, so in one day we saw the addition of 110 prefixes, but they were aligned such that the size of a properly cidr-aggregated table dropped by 943. this is quite a trick. what does it all mean? > ... > Aggregation Summary > The algorithm used in this report proposes aggregation only > when there is a precise match using the AS path, so as > to preserve traffic transit policies.

(i've only listed those who could reduce their impact on the global routing table by 80% or more... as you all saw, the list *was* longer.) there are any number of unemployed bgp experts haunting this mailing list looking for post-dotbomb work. many of them would accept work as short term consultants to help you folks get down under the 80% level. just ask! -- Paul Vixie
