no area area-id nssa
no area area-id
area-id Identifier of the area for which authentication is to be enabled. The identifier can be specified as either a decimal value or an IP address.
no-redistribution (Optional) Used when the router is a NSSA ABR and you want the redistribute command to import routes only into the normal areas, but not into the NSSA area.

originate(Optional) Used to generate a Type 7 default into the NSSA area. This argument only takes effect on NSSA ABR.
No NSSA area is defined.

To remove the specified area from the software configuration, use the command no area area-id (with no other keywords). That is, no areaarea-id removes all area options, such as area authentication, area default-cost, area nssa , area range, area stub, and area virtual-link.
The following example enables NSSA authentication on area 1:
router ospf1 redistribute rip subnets network 172.19.92.0.0.0.0.255 area 1 area 1 nssa
