In GNS3, the default name of a Router is R1 and on a real device, it is Router. A +1 number is added to the default name of each device you just added to this program.

You can rename your devices for more organized network topologies.

To change the Hostname:

Step 1: Switch to privileged mode using the “configure terminal” command in CLI.

Step 2: To change R1 to ARouter, execute “hostname ARouter”.
