Rolling Back the Configuration over a Specified Number of Commits
When you roll back the configuration over a specific number of commits, you do not have to enter a
specific commit ID. Instead, you specify a number x, and the software undoes all configuration changes
made in the last x committed configuration sessions. The rollback process rolls back the configuration,
commits the rolled-back configuration, and creates a new commitID for the previous configuration.

rollback changes command.
To roll back to the last x commits made, go to EXEC or administration EXEC mode and type the
rollback configuration last x command; x is a number ranging from 1 to the number of saved commits
in the commit database.
In the following example, a request is made to roll back the configuration changes made during the
previous two commits:
RP/0/RSP0/CPU0:router# rollback configuration last 2

Loading CommitID Configuration Changes to the Target Configuration
If the changes saved for a specific commitID are close to what you want, but a rollback is not appropriate,
you can load the configuration changes for a commitID into the target configuration, modify the target
configuration, and then commit the new configuration. Unlike the rollback process, the loaded changes
are not applied until you commit them.
