Assigning Area ID on an InterfaceTo assign the OSPFv3 process to an interface, use the following command.The ipv6 ospf area command enables OSPFv3 on an interface and places the interface in the specified area. Additionally, thecommand creates the OSPFv3 process with ID on the router. OSPFv2 requires two commands to accomplish the same tasks — therouter ospf command to create the OSPF process, then the network area command to enable OSPFv2 on an interface.NOTE: The OSPFv2 network area command enables OSPFv2 on multiple interfaces with the single command.
