Save Configuration Changes and Activate the Configuration

To save software configuration changes to the configuration database and activate the configuration on the router, use the commit configuration mode command:

user@host# commit 

commit complete

The configuration is checked for syntax errors. If the syntax is correct, the configuration is activated and becomes the current, operational router configuration. If the configuration contains syntax errors, a message indicates the location of the error and the configuration is not activated. You must correct the error before recommitting the configuration.
