Its an actual across-the-board drop. If you eliminate the puny bcasts (less
then 10 dupes) the numbers are even better. I've got a project setup to
automatically scan everything in the bgp routing table, grab contact
information for the UPLINK (99.9% of those bcasts remaining are ones with
dud contact info), send out aggregated emails to said uplinks, and maintain
a database of useful statistics. The only thing I'm waiting on is certain
persons coughREIDcough coughSTEVEcough to get off their arses and finish
what they said they would a couple months ago. =)
