This video shows you how to configure the hostname name of the Cisco Router / Switch using GNS3.
Changing the names of Cisco Routers or Switches prevents complexity for future network changes.
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”.
– R1(config)# hostname ARouter
Step 3: After configuring the name of your device, use the wr command to save the running configuration.
– ARouter# wr
You can rename your Router name by following these steps.
