    The system view is displayed.

  2. Run:

    ospfv3 [ process-id ]

    The OSPFv3 process view is displayed.

  3. (Optical) Run:

    lsa-forwarding-address { standard | zero-translate }

    The OSPFv3 forwarding address (FA) function is enabled.

  4. Run:

    area area-id

    The OSPFv3 area view is displayed.

  5. Run:

    nssa [ default-route-advertise [ cost cost | type type | tag tag ] * | no-import-route | no-summary | translator-always | translator-interval translator-interval | set-n-bit | suppress-forwarding-address  ] *

    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.
