That was my assumption when I checked the "UCLA is wrong" button on the form. We only have one downstream, but it's a distinct ASN so that says "not stub" to me. Mike Randy top posting - will wonders never cease.

OK,a buckety of salt. From my pov, a stub has zero downstreams. randy, on iPhone On Jun 24, 2009, at 10:39, Ricardo Oliveira <rveloso () cs ucla edu> wrote:Jack, Please give me your ASN and i'll double check our data. As long as the network has 4 or less downstreams, it's being labeled as
"stub".

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. :) Jack
