An area is configured as an NSSA.

Follow-up Procedure

If an area is configured as an NSSA, all switches in the area must be configured with the NSSA attribute.

The area may be updated after NSSA attributes are configured or deleted. Therefore, the NSSA attributes can be re-configured or deleted only after the last update to the area is complete.
