Configuring an NSSA area
A stub area cannot redistribute routes. Configure the area as an NSSA area to allow for route redistribution by keeping other stub area characteristics.
To configure an NSSA area:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter OSPF view. | ospf [ process-id | router-id router-id | vpn-instance vpn-instance-name ] * | N/A |
3. Enter area view. | area area-id | N/A |
4. Configure the area as an NSSA area. | nssa [ default-route-advertise | no-import-route | no-summary | translate-always | translator-stability-interval value ] * | Not configured by default. You must use the nssa command on all the routers attached to an NSSA area. |
5. Specify a cost for the default route advertised to the NSSA area. | default-cost cost | Optional. 1 by default. The default-cost command is available only on the ABR/ASBR of an NSSA area. |
