What is the maximum number of configurations, by default, that can be recovered using the rollback command in Junos?

The rollback command in Junos allows users to recover previous configurations to restore the system to a known state. By default, Junos stores the last 50 committed configurations, enabling users to revert back to any of those previous states as needed. This feature is particularly useful for troubleshooting and maintaining network stability, as it allows quick recovery from potential misconfigurations or errors during updates. Understanding the rollback mechanism and the capacity to recover configurations is essential for network management, especially in environments where changes are frequent and need to be carefully controlled. This design emphasizes reliability in configuration management by providing multiple recovery options.
