| Argument | Type | Description |
|---|
| name | string | The name of the area |
| instance ( mandatory ) | enum | Name of the OSPF instance this area belongs to. |
| area-id | ipAddr | OSPF area identifier. If the router has networks in more than one area, then an area with area-id=0.0.0.0 (the backbone) must always be present. The backbone always contains all area border routers. The backbone is responsible for distributing routing information between non-backbone areas. The backbone must be contiguous, i.e. there must be no disconnected segments. However, area border routers do not need to be physically connected to the backbone - connection to it may be simulated using a virtual link. |
| type | enum (default | stub | nssa) | The area type. Read more on the area types in the OSPF user guides. |
| no-summaries | switch | Flag parameter, if set then the area will not flood summary LSAs in the stub area. |
| default-cost ( unset ) | num | Default cost of injected LSAs into the area. If the value is not set, then stub area type-3 default LSA will not be originated. |
| nssa-translator ( unset ) | enum (candidate | no | yes) | The parameter indicates which ABR will be used as a translator from type-7 to type-5 LSA. Applicable only if area type is NSSA.
- yes - the router will be always used as a translator.
- no - the router will never be used as a translator.
- candidate - OSPF elects one of the candidate routers to be a translator.
