The nature of an NSSA stops type 5's from coming in. An NSSA gets ONLY
LSA3's from the BB.
An NSSA TOTALLY STUB gets only a default route from the NSSA TOTALLY ABR.

Subject: Re: Ospf Rules Regarding NSSA ASBR
So at this point I guess I am asking myself is if I got to an ospf NSSA
ASBR and issue the command " show ip ospf database " and I see 20 Extenal
Type 5 LSA's , what would stop this router from converting them into OSPF
type 7 and sending them into the nssa area ?
