You configured an interface with an IP address and committed the change. You then committed a change that added an exception in a firewall filter to allow this network through the filter. You realize that this work was done on the wrong router.
How do you undo all these changes?
To undo the last two committed changes, you should use 'rollback 2'. This command reverts the configuration to the state it was in before the last two changes were made.
Roll back 0 becomes roll back 1, then it becomes rollback 2, we must pay attention to the question, because the configuration made was for another device
