Junos Rollback

The Junos command that loads a previously committed configuration (rollback 0-49) into the candidate.

Definition

Junos keeps the active configuration as rollback 0 and up to 49 previous versions. rollback N replaces the candidate; a commit is still required to activate it. rollback 0 discards uncommitted changes.

Example

rollback 1 ; commit

Exam tip

Rollback alone does nothing to the running device until you commit.
