Parameter
router-id : Router ID that is a 32-bit unsigned integer.
Description
Using router id command, you can configure the ID of a router running the OSPF
protocol. Using undo router id command, you can cancel the router ID that has been
set.
By default, if the LoopBack interface address exists, the system chooses the LoopBack
address with the greatest IP address value as the router ID; if no LoopBack interface
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.
Note:
The modified router ID will not be valid unless OSPF is re-enabled.

Example
# Set the router ID to 10.1.1.3.
