Marcus,
My first question is "how is r2 getting the default-route
from r1 now...? There's actually a couple of ways to get your desired
results in this scenario.
1. If all you need is a default-route to propagate into your rip domain
then the "area X nssa default-information originate on the NSSA ABR should
get this done.
2. If you have specific requirements to filter IA(type 3&4 LSAs) then the
"area X nssa no-summary" will fulfill this requirement.
Check out Doyle's book on page 537-544, there are some great examples
there..
HTH
Nigel..
