Sounds to me like one of your providers is not feeding you the full
internet routing table. Have you checked with them to see if they are
providing you that?

Subject: Determine difference between 2 BGP feeds
Hi,
We receive a BGP feed from different providers on two=20
different routers. While one seems to be a reasonable amount
of feeds after reviewing the CIDR report, the other is anywhere
from 3K to 10K more routes.=20
Is there a utility that I can use that will pull the
routes off each router (Foundry preferred), and then compare=20
them as best it can to see why there is such a difference?=20
I can understand a handful of routes over what CIDR says,=20
but a minimum of 3K more?
Thanks, Tuc/TBOH
