Area 0.0.0.0
Any OSPF network that contains more than one area is required to have an area configured as area 0, also called the backbone. All areas in an autonomous system must be connected to the backbone. When designing networks, you should start with area 0, and then expand into other areas.
The backbone allows summary information to be exchanged between ABRs. Every ABR hears the area summaries from all other ABRs. The ABR then forms a picture of the distance to all networks outside of its area by examining the collected advertisements, and adding in the backbone distance to each advertising router.
When a VLAN is configured to run OSPF, by default you must assign it to an area.
The following command associates the VLAN accounting with an OSPF area:
configure ospf vlan accounting area 0.0.0.6
