Upgrade rsc files
The file upgrade.rsc is the key component to mass roll-outs of CPE setting changes and script additions. By creating this file and uploading to main mikrotik AP/router, changing hundreds of CPE's within a few seconds is only moments away. Enable the trigger IP (in our case 172.16.0.1), sit back and watch all your CPE's log in via ftp, collect the upgrade.rsc file and import it on all the CPE's.
Below are few examples of upgrade.rsc files. You MUST test these on a single local CPE to see that no negative reactions occur, before rolling out for network wide implementation. As always, used at your own risk.
