The Routing Engine runs Junos OS. Software processes that run on the Routing Engine
maintain the routing tables, manage the routing protocols used on the router, control
the router interfaces, control some chassis components, and provide the interface for
system management and user access to the router.
You can install one or two Routing Engines in the router. If two Routing Engines are
installed, one functions as the master and the other acts as the backup. The Routing
Engines install into the upper rear of the chassis in the slots labeled
