Information
You can configure an arbitrary value in the IP address format for each router. However, each
router ID must be unique. If you use this command on an OSPF router process, which is already
active (that is, has neighbors), a prompt reminding you that changing the router-id brings down
the existing OSPF adjacency. The new router ID is effective at the next reload.
