Actually I'd like to take back what I said. I think the /32 entry is
supposed to be in the routing table for the interface. The thing I was
saying about the virtual-link though is good to note. Try labbing it up and
see what I mean. The /32 is supposed to be there though. I believe this is
just the nature of how OSPF works (I'm sure there is a more technical
explaination)
