Use An Alternate Source Location For A Script | Junos OS

In addition to updating a script from the master source defined by the source statement, you also can update a script from an alternate location using the set refresh-from configuration mode command or the request system scripts refresh-from operational mode command. This is convenient when, for example, the master source cannot be accessed due to network issues or other problems.

The update operation occurs as soon as you issue either the set refresh-from configuration mode command or the request system scripts refresh-from operational mode command. When you issue the command, the device immediately attempts to connect to the specified URL and retrieve a copy of the file. The copy overwrites the local script stored in the scripts directory on the device. If a copy of the source is not available at the remote URL, that script is not updated and a warning is issued. For commit scripts, the updated commit script is executed when you next issue the commit command.

Issuing the set refresh-from command does not add the refresh-from statement to the configuration. Thus the set refresh-from command behaves like an operational mode command by executing an operation, instead of adding a statement to the configuration.

If a device has dual Routing Engines and you want to update the script on both Routing Engines, you must issue the set refresh-from command on each Routing Engine separately. Alternatively, you can refresh the scripts on the requesting Routing Engine and then use either the request system scripts synchronize operational mode command to synchronize scripts to the other Routing Engine or the commit synchronize scripts configuration mode command to synchronize all scripts to the other Routing Engine when you commit and synchronize the configuration. In operational mode, you can also use the request system scripts refresh-from command with the sync option to refresh the script on both Routing Engines.

To update one or more scripts using the set refresh-from configuration mode command:
