see page 538 of Doyle's routing TCP-IP
quote "area x nssa no-summary"
"To turn area into a somewhat schizophrenically named ""totally stubby
not-so-stubby"" area
This command eliminates all inter-area routes and adds a default from the
ABR

I'm not sure about your problem with "no-summary" but I know that an area
can't be defined as both stub and NSSA...The point of NSSA is that the area
is inherently stub, but it will allow type 7 LSA's to pass through to
advertise about other autonomous systems.
