Connectivity Guide

3 Enter the interface information to congure 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 conguration 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 specic 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 congurations that already exist on the interface. If you move the interface from one VRF instance to
another without removing these existing Layer3 or OSPF congurations, these congurations do not take eect in the new VRF
instance.
Consider a scenario where the OSPF instance 100 is congured on the default VRF instance and the OSPF instance 200 is congured
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 conguration to which the interface eth1/1/1 is currently attached to.
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 becomes eective immediately.
Assign the router ID for the OSPFv3 process in ROUTER-OSPFv3 mode.
router-id ip-address
