Parameters
router-id: Router ID in IP address format.
Description
Use the router-id command to specify a router ID.
Use the undo router-id command to remove the router ID.
To run BGP protocol, a router must have a router ID, which is an unsigned 32-bit integer, the unique ID
of the router in the AS.
You can specify a router ID manually. Otherwise, the system selects the highest IP address among
loopback interface addresses as the router ID. If no loopback interface addresses are available, the
system selects the highest IP address among physical interface IP addresses as the router ID. HP
recommends specifying a loopback interface address as the router ID to enhance network reliability.
If the interface whose IP address is selected as the router ID or the manual router ID is deleted, the system
selects a new router ID for the router.
Examples
# Specifies the Router ID as 10.18.4.221.
