Just curious if anyone has noticed the leaking of the more specific routes of AT&T's IP space in their BGP table.  Here's what we're seeing in ours:

#s ip ro 12.0.0.0
Routing entry for 12.0.0.0/8, 589 known subnets
  Variably subnetted with 9 masks

B       12.23.26.0/23 [20/0] via x.x.x.x
B       12.28.18.0/24 [20/0] via x.x.x.x
B       12.33.46.0/24 [20/0] via x.x.x.x, etc.....

I should just see the aggregation of the /8, but something changed on 8/7/2001 at precisely 8 AM Eastern time.  The same is with their 24/8 and their other networks as well.  I have about 40,000 superfluous networks in my BGP table.  ;)
