Ick. Nothing was right. Reported as mixed, though that may be my fault 
and not your testing. Hmmm. Or your test didn't take some things into 
account like changes over time. Normally I keep a default route 
available, but due to changing IGP internally I actually have a default 
which points interior from the edge routers. So when I shut down the 
last BGP session on the old cisco, the defaults to the transits went away.

  Was also reported as a stub. Glad to know that I don't have BGP 
customers. Oh, wait, I do. :)
