Command to enable OSPFv3 on an interface and assigning one or more VLANs to each area

After you define an OSPFv3 area, you can assign one or more VLANs to it. When a VLAN is assigned to an area, all currently configured IPv6 addresses in the VLAN are automatically included in the assignment.
NOTE:

All static VLANs configured on a routing switch configured for OSPFv3 must be assigned to one of the defined areas in the AS.
