Hehe sorry for the flashbacks ;) In this particular instance, we had a BGP peer that was slipping us a default route. That route was actually making it into the BGP tables locally (but not chosen as best route thankfully!). Guess I need to look at tighter filtering again geesh.
So with the default route in the BGP tables, when the 7200 was doing an ASN lookup for local addresses it was matching 0.0.0.0/0 from BGP and associating that to their ASN.
