You're probably looking for the ip ospf database-filter all out command.
And how the summary LSA with 0/0 would get to the spoke router if that
is filtered out?

This will effectively keep type 5 LSAs from being advertised into the NSSA.

I have a question. I have recently setup a second OSPF area. The ABR has

The routers get a default route to the ABR via default information
