Configuring OSPFv3 on the routing switch

Create the OSPFv3 instance and enter the OSPFv3 configuration context. From this context, you can proceed with other OSPFv3 configuration.

Prerequisites

You must be in the global configuration context, as indicated by the switch(config)# prompt to create the OSPFv3 instance and enter the OSPFv3 configuration context.
To configure a router ID, and other OSPFv3 configuration you must be in the OSPFv3 router configuration context, as indicated by the switch(config-ospfv3-1 )# prompt.

Procedure

Create the OSPFv3 instance and enter the OSPFv3 configuration context using the following command. For command details, see router ospfv3.
router ospfv3 <instance-tag> [vrf <vrf-name>]
For example, the following command creates OSPF instance 1.
```
switch(config)# router ospfv3 1
switch(config-ospfv3-1)#
```
Configure a global router ID using the following command. For command details, see router-id.
router-id <router_address>
For example, the following command sets the router ID to 1.1.1.1.
```
switch(config-ospfv3-1)# router-id 1.1.1.1
```
Optionally, if the OSPFv3 process was disabled (it is enabled by default), enable the OSPFv3 process using the following command.
enable

For command details, see enable. (Refer to disable for disabling the OSPFv3 process).
