router-id: Router ID that is a 32-bit unsigned integer.

Use the router id command to configure the ID of a router running the OSPF 
protocol. Use the undo router id command to cancel the router ID that has been 
set.

By default, if LoopBack interface addresses exist, the system chooses the LoopBack 
address with the greatest IP address value as the router ID; if no LoopBack 
interface is configured, then the address of the physical interface with the greatest 
IP address value will be the router ID.

Router ID is a 32-bit unsigned integer that uniquely identifies a router in an OSPF 
autonomous system. The user can specify the ID for a router. If the user doesn’t 
specify router ID, the router will automatically select one from configured IP 
address as the ID of this router. If no IP address is configured for any interface of 
the router, the router ID must be configured in OSPF view. Otherwise, OSPF 
protocol cannot be enabled.

When the router ID is configured manually, the IDs of any two routers cannot be 
same in the autonomous system. So, the IP address of certain interface might as 
well be selected as the ID of this router.
