area <AREA-ID> nssa

Description

Creates the NSSA area (Not So Stubby Area) with <AREA-ID> if not present. If area is present and not NSSA area, this command changes the area type to NSSA area. If no-summary is used, area type will be NSSA No-Summary.

The no form of this command unsets the area type as NSSA. That is, the configured area will be changed to default normal area. The no area <AREA-ID> nssa no-summary command enables sending inter-area routes into NSSA, but will not unset the area as NSSA.
