Copy TFTP Running-config
This command lets you merge your backed up configuration on a TFTP server with your running configuration..
Router#copy tftp running-config
In the below example the backed up configuration on a TFTP server is merged with the running config on the router.

9789 bytes copied in 7.905 secs (1238 bytes/sec)
Below is a screenshot of the TFTP server sending the configuration. In case your wondering, the errors are due to various VPN configurations I have on my on router that can’t be merged.
