Open Shortest Path First (OSPFv2 and OSPFv3) | 727Enable IPv6 Unicast RoutingAssign IPv6 addresses on an interfaceAssign Area ID on interfaceThe ipv6 ospf area command enables OSPFv3 on an interface and places the interface in the specifiedarea. Additionally, it creates the OSPFv3 process with ID on the router. OSPFv2 required two commandsare required to accomplish the same tasks: the router ospf command to create the OSPF process, then thenetwork area command to enable OSPFv2 on an interface. Note that the OSPFv2 network area commandcan enable OSPFv2 on multiple interfaces with the single command, whereas the OSPFv3 ipv6 ospf areacommand must be configured on each interface that will be running OSPFv3.Command Syntax Command Mode Usageipv6 unicast routing CONFIGURATION Enables IPv6 unicast routing globally.Command Syntax Command Mode Usageipv6 address ipv6 address CONF-INT-type slot/port Assign IPv6 address to the interface.IPv6 addresses are normally written aseight groups of four hexadecimal digits,where each group is separated by a colon(:).FORMAT: A:B:C::F/128no shutdown CONF-INT-type slot/port Bring the interface up.Command Syntax Command Mode Usageipv6 ospf process-id area area-id CONF-INT-type slot/port Assign the OSPFv3 process and anOSPFv3 area to this interface.process-id: The Process ID numberassigned above.area-id: the area ID for this interface.
