Compare and commit a Junos configuration Start by checking the active interface state on the Junos router. Enter configuration mode, add an address and compare the candidate with the active configuration. The address is visible in the candidate, and the operational interface still has no new address. Commit the candidate and confirm that the address is now active. Stage a different address, compare it, then discard the edit with rollback zero. Reopen the lab and confirm that the committed address is still active.
