In the event that you have lost the configuration on your Cisco device, restoration is straight forward assuming of course you had made a backup. There are 2 ways to restore the configuration to put our device back to normal

 

                1/ Copy and paste the backup configuration directly to the device

                2/ Copy the configuration from a TFTP server to the device.

 

In both cases, make sure you save your configuration afterwards using either “copy run start” or “write”.

 

Below is an example of restoration from a TFTP server. You will notice the router name is “Router” – the default hostname for a router without configuration. After the restoration is completed, you will notice the hostname goes back to the configured value.
