A very simple Method to roll out configfiles on a bunch of Router:
The Router will try to download a config file from a ftp server with a unique part in the URL. After the File was downloaded successfully it will be deleted on the remote ftp server.
This way you won't have a endless download.
This Script can be used with various triggers: periodicly every XX min, after wan-up, sdk-startup and so on
