or

to reload at a specific time.

This command instructs the router to reboot in 30 minutes.

Proceed to configure the router as needed. As long as no configuration changes are saved, the router will revert to its previous configuration when it reloads.

If configuration changes are successful,

will stop the pending reload.

If configuration changes cause a loss of connectivity, the local side can be easily reset to the previous configuration. When the router reloads, connectivity will be restored.
