router-id: Router ID in IP address format.  

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. If not, the system selects an IP address as the router ID. The 

selection sequence is the highest IP address among loopback interface addresses; if not available, then 

the highest IP address of interfaces. It is recommended to specify a loopback interface address as the 

router ID to enhance network reliability. 

Only when the interface with the selected Router ID or the manual Router ID is deleted will the system 

select another ID for the router. 

# Specifies the Router ID as 10.18.4.221.
