Commit Scripts and the JUNOS Software Commit Model

The JUNOS software uses a commit model to update the router's configuration. This model allows you to make a series of changes to a candidate configuration without affecting the operation of the routing platform. When the changes are complete, you can commit the configuration. The commit operation saves the candidate configuration changes into the current configuration.

When you commit a set of changes in the candidate configuration, two methods are used to forward these changes to the current configuration:

• Standard commit model—Used when no commit scripts are active on the routing platform.
• Commit script model—Incorporates commit scripts into the commit model.
