In Junos configuration, what does the term 'commit confirmed' mean?

The term 'commit confirmed' in Junos configuration indicates that the configuration changes made will automatically revert after a specified timeout unless a permanent commit is issued. This feature is particularly useful during testing or when making significant changes, as it allows for a safeguard against potential issues that could arise from faulty configurations. If a user forgets to commit permanently within the specified timeout period, the system will revert to the previous stable configuration, thereby minimizing the risk of extended downtime caused by misconfigurations.

This safety feature allows network engineers to validate their configuration changes and provides a way to ensure the network remains stable during unforeseen issues.
