Also keep in mind that in a regular NSSA the ABR does not originate
a default route automatically. With the stub, totally-stubby, and
not-so-totally-stubby areas the ABR does automatically originate a default
route. This means without additional configuration all devices in the NSSA
will lose connectivity to external OSPF routes that are originated in other
areas, unless they already have an alternate route to them aside from a
route via the ABR.

Use NSSA when you want your Area to be stub, yet be able to redistribute
external routes. An ASBR can not be in a stub area, so you can use an NSSA
to still benefit from the properties of a stub area yet with the ability to
have an ASBR in the area.
