Syntax
router id router-id

View

Parameters
router-id: Router ID, in dotted decimal notation.
Description
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.
If the router-id command is not used, a router ID is set following these rules:
z If loopback interfaces configured with IP addresses exist, the greatest loopback interface IP
address will be used as the router ID.
z If no loopback interface IP address exists, the greatest IP address of other interfaces will be used
as the router ID, regardless of whether the interfaces are up or down.
z A new router ID is selected only after the existing router ID is deleted or modified. Other cases, for
example, when the interface with the router ID goes down, when a loopback interface address is
configured after a non-loopback interface address is selected as the router ID, or when a greater
interface IP address is configured, cannot trigger a new router ID selection process,
z To validate a new router ID, you need to execute the reset command.
