If you have a cisco router, and an expect script, or similar, that collects the output of "show ip bgp", then an output analyzer is available at www.telstra.net/ops/bgp/bgp-parse.c.txt (You'll need gnuplot and whois). The program generates an html report - as per www.telstra.net/ops/bgp
Ironically 1221 is the worst offender out there for lack of aggregation and has been for some time if you look at the Bates reports :)
And it was a suspicion that Tony's report's did not really expose the entire set of issues regarding route aggregation which prompted me to look at proxy aggregation in further detail. Ironically, if you take AS path rather than AS origin as the aggregation condition then its AS701 which appears to have the largest number of aggregation potentials - but even this is not the entire story.
