# area > RouterOS directory reference for /routing/ospf/area. ----------- ## routing/ospf/area **Type:** Directory disabled inactive dynamic transit-capable The name of the area Name of the OSPF instance this area belongs to. 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. The area type. Read more on the area types in the [OSPF user guides](../../../../user-guides/routing-and-networking-protocols/unicast/ospf/areas-and-virtual-links.md). Flag parameter, if set then the area will not flood summary LSAs in the stub area. 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. 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.
