Redundant Routing Engines Overview
Inspect redundant Routing Engines to minimize system process failures.
Redundant Routing Engines are two Routing Engines that are installed in the same router.
One functions as the master, while the other stands by as a backup should the master
Routing Engine fail. By default, the Routing Engine in slot 0 is the master (RE0) and the
one in slot 1 is the backup (RE1).
