Specifying the key rollover timer

The key rollover timer can be configured so that rekeying takes place on all the nodes at the same time and the security parameters are consistent across all the nodes.

Enter the configure terminal command to access global configuration mode.
```
device# configure terminal
```

Enter the ip router-id command to specify the router ID.
```
device(config)# ip router-id 10.11.12.13
```

Enter the ipv6 router ospf command to enter OSPFv3 router configuration mode and enable OSPFv3 on the device.
```
device(config)# ipv6 router ospf
```

Enter the key-rollover-interval command and specify the desired interval to set the timing of the configuration changeover.
```
device(config-ospf6-router)# key-rollover-interval 240
```

The following example sets the timing of the configuration changeover to 240 seconds (4 minutes).

device# configure terminal
device(config)# ip router-id 10.11.12.13
device(config)# ipv6 router ospf 
device(config-ospf6-router)# key-rollover-interval 240
