A、In interface configuration mode, the OSPFv3 area ID combination assigns interfaces to OSPFv3 areas. B、In router configuration mode, the network wildcard area ID combination assigns networks to OSPFv3 areas. C、In interface configuration mode, the IPv6 OSPF process area ID combination assigns interfaces to OSPFv3 areas. D、In router configuration mode, the IPv6 OSPF interface area ID combination assigns interfaces to OSPFv3 areas.
