Configuration Task List for OSPFv3(OSPF for IPv6)This section describes the configuration tasks for Open Shortest Path First version 3 (OSPF for IPv6) on theswitch.The configuration options of OSPFv3 are the same as those options for OSPFv2, but you may configureOSPFv3 with differently labeled commands. Specify process IDs and areas and include interfaces andaddresses in the process. Define areas as stub or totally stubby.The interfaces must be in IPv6 Layer-3 mode (assigned an IPv6 IP address) and enabled so that they can sendand receive traffic. The OSPF process must know about these interfaces. To make the OSPF process aware ofthese interfaces, assign them to OSPF areas.The OSPFv3 ipv6 ospf area command enables OSPFv3 on the interface and places the interface in anarea. With OSPFv2, two commands are required to accomplish the same tasks — the router ospfcommand to create the OSPF process, then the network area command to enable OSPF on an interface.NOTE: The OSPFv2 network area command enables OSPF on multiple interfaces with the singlecommand. Use the OSPFv3 ipv6 ospf area command on each interface that runs OSPFv3.All IPv6 addresses on an interface are included in the OSPFv3 process that is created on the interface.Enable OSPFv3 for IPv6 by specifying an OSPF process ID and an area in INTERFACE mode. If you have notcreated an OSPFv3 process, it is created automatically. All IPv6 addresses configured on the interface areincluded in the specified OSPF process.NOTE: IPv6 and OSPFv3 do not support Multi-Process OSPF. You can only enable a single OSPFv3process.Enabling IPv6 Unicast RoutingTo enable IPv6 unicast routing, use the following command.• Enable IPv6 unicast routing globally.CONFIGURATION modeipv6 unicast routingAssigning IPv6 Addresses on an InterfaceTo assign IPv6 addresses to an interface, use the following commands.1 Assign an IPv6 address to the interface.CONF-INT-type slot/port modeOpen Shortest Path First (OSPFv2 and OSPFv3) 768
