I will do that on Monday. ip classless is definitely configured. It
does appear to be some kind of summary route, is there a way to so no
summary route other then ip classless? I am running single area OSPF
so I don't understand why there is any authosummarization.

THanks.

do you have an "ip default-network" command configured ?

It is a classful command and if you have a route to a subnet of that
network, I believe IOS will install the major network from the
defualt-network command into the routing table as a static route.
