OSPFv3
OSPFv3 is an IPv6 link-state routing protocol that supports IPv6 unicast address families (AFs). OSPFv3 is disabled by default. You must
congure at least one interface, either physical or loopback. The OSPF process automatically starts when OSPFv3 is enabled for one or
more interfaces. Any area besides area 0 can have any number ID assigned to it.
Enable OSPFv3
1 Enable OSPFv3 globally and congure an OSPFv3 instance in CONFIGURATION mode.
router ospfv3 instance-number
2 Enter the interface information to congure the interface for OSPFv3 in INTERFACE mode.
interface ethernet node/slot/port[:subport]
3 Enable (or bring up) the interface in INTERFACE mode.
no shutdown
4 Disable the default switchport conguration and remove it from an interface or a LAG port in INTERFACE mode.
no switchport
5 Enable the OSPFv3 on an interface in INTERFACE mode.
ipv6 ospfv3 process-id area area-id
• process-id — Enter the OSPFv3 process ID for a specic OSPFv3 process (1 to 65535).
• area-id — Enter the OSPF area ID as an IP address (A.B.C.D) or number (1 to 65535).
Enable OSPFv3
OS10(config)# router ospfv3 100
OS10(config-router-ospfv3-100)# exit
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# no shutdown
OS10(conf-if-eth1/1/1)# no switchport
OS10(conf-if-eth1/1/1)# ipv6 ospfv3 300 area 0.0.0.0
Assign Router ID
You can assign a router ID for the OSPFv3 process. Congure an arbitrary value in the IP address format for each router. Each router ID
must be unique. Use the xed router ID for the active OSPFv3 router process. Changing the router ID brings down the existing OSPFv3
adjacency. The new router ID becomes eective immediately.
• Assign the router ID for the OSPFv3 process in ROUTER-OSPFv3 mode.
router-id ip-address
