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. ;)
