    Meaning

    The command output shows the status of the Routing Engines: RE0 is Master and RE1 is Backup.

    You can also use the show chassis environment routing-engine command. The Current State field indicates which Routing Engine is master and which is backup.

    For M40e and M160 routers, you can also use the show chassis craft-interface command. The command output shows the master and backup Routing Engine LED status.
