Connectivity Guide
3 Enter the interface information to congure 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 conguration 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 specic 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 rst
remove the OSPF or Layer3 congurations that already exist on the interface. If you move the interface from one VRF instance to
another without removing these existing Layer3 or OSPF congurations, these congurations do not take eect in the new VRF
instance.
Consider a scenario where the OSPF instance 100 is congured on the default VRF instance and the OSPF instance 200 is congured
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 rst remove the OSPF
area conguration to which the interface eth1/1/1 is currently attached to.
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
