We're only picking up the ones tagged with MCI's internal AS's: *> 204.70.0.0/15 198.32.136.12 150 3561 i *> 204.70.128.0/21 198.32.136.12 150 3561 4292 i *> 204.70.138.0 198.32.136.12 150 3561 4281 i *> 204.70.139.0 198.32.136.12 150 3561 4286 ? *> 204.70.140.0 198.32.136.12 150 3561 4286 ? *> 204.70.141.0 198.32.136.12 150 3561 4286 ? *> 204.70.142.0 198.32.136.12 150 3561 4286 ? *> 204.70.144.0 198.32.136.12 150 3561 4286 i *> 204.70.145.0 198.32.136.12 150 3561 4286 ? *> 204.70.240.0/20 198.32.136.12 150 3561 4292 i Notice we're picking up the /15 adv. I'm sure you can see it with a 255.254.0.0 query mask. I see your stuff: *> 204.71.144.0/21 198.32.136.12 150 3561 3927 i *> 204.71.152.0 198.32.136.12 150 3561 3927 i *> 204.71.153.0 198.32.136.12 150 3561 3927 i *> 204.71.155.0 198.32.136.12 150 3561 3927 i *> 204.71.156.0/22 198.32.136.12 150 3561 3927 i You have 204.71.144.0/20. No aggregation? ;) Sounds like a route-map doesn't have a no-adv tag set right at MCI. You're seeing all their IBGP stuff. For me, it seems like kind of a waste to adv a bunch of specifics if they're internal anyway :) The ones above all use MCI's internal AS's. I'd just like to see the /15, nothing else. rob.
