OSPFv3
OSPFv3 is an IPv6 link-state routing protocol that supports IPv6 unicast address families (AFs). OSPFv3 is disabled by default. You must
congure 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 congure an OSPFv3 instance in CONFIGURATION mode.
router ospfv3 instance-number
2 Enter the interface information to congure 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 conguration and remove it from an interface or a LAG port in INTERFACE mode.
no switchport
5 Assign an IPv6 address to the interface in INTERFACE mode. If you are using a Loopback interface, see Loopback Interfaces
ipv6 address ipv6-address/mask
6 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 specic 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 address fe80::20c:29ff:fe0a:d59/64
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. Congure 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 is eective at the next reload.
• Assign the router ID for the OSPFv3 process in ROUTER-OSPFv3 mode.
