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
  5. Disable the default switchport configuration and remove it from an interface or a LAG port in INTERFACE mode. 
    no switchport
  6. Associate the interface with the non-default VRF instance that you created earlier. 
    ip vrf forwarding vrf-name
  7. Enable the OSPFv3 on an interface. 
    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)# ip vrf vrf-blue
OS10(config-vrf-blue)# router ospfv3 100 vrf vrf-blue
OS10(config-router-ospfv3-100)# exit
OS10(config)#  interface ethernet 1/1/2
OS10(conf-if-eth1/1/2)# no shutdown
OS10(conf-if-eth1/1/2)# no switchport
OS10(conf-if-eth1/1/2)# ip vrf forwarding vrf-blue
OS10(conf-if-eth1/1/1)# ipv6 ospfv3 300 area 0.0.0.0
NOTE

If you want to move an interface associated with one VRF instance to another default or non-default VRF instance, you must first remove the OSPF or Layer3 configurations that already exist on the interface. If you move the interface from one VRF instance to another without removing these existing Layer3 or OSPF configurations, these configurations do not take effect in the new VRF instance.

Consider a scenario where the OSPF instance 100 is configured on the default VRF instance and the OSPF instance 200 is configured on the non-default VRF instance named VRF-Red. The interface eth1/1/1 on the default VRF instance is attached to an OSPF process 100 area 1. In this scenario, if you want to move eth1/1/1 from the default VRF instance to VRF-Red, you must first remove the OSPF area configuration to which the interface eth1/1/1 is currently attached to.
