OSPFv3
OSPFv3 is an IPv6 link-state routing protocol that supports IPv6 unicast address families (AFs). OSPFv3 is disabled by default.
You must configure 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 configure an OSPFv3 instance in CONFIGURATION mode.
router ospfv3 instance-number
2. Enter the interface information to configure the interface for OSPFv3 in INTERFACE mode.
interface ethernet node/slot/port[:subport]
3. Enable the interface in INTERFACE mode.
no shutdown
4. Disable the default switchport configuration 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 specific OSPFv3 process, from 1 to 65535.
area-id Enter the OSPF area ID as an IP address in A.B.C.D format or number, from 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
Enable OSPFv3 in a non-default VRF instance
1. Create the non-default VRF instance in which you want to enable OSPFv3:
ip vrf vrf-name
CONFIGURATION Mode
2. Enable OSPFv3 in the non-default VRF instance that you created earlier and configure an OSPFv3 instance in VRF
CONFIGURATION mode.
router ospfv3 instance-number vrf vrf-name
3. Enter the interface information to configure the interface for OSPFv3 in INTERFACE mode.
interface ethernet node/slot/port[:subport]
4. Enable the interface in INTERFACE mode.
no shutdown
