The host subsystem provides routing protocol processes, as well as software processes that control the
router's interface, the chassis components, system management, and user access to the router. These
routing processes run on top of a kernel that interacts with the Packet Forwarding Engine. The MX204
host subsystem consists of a single built-in Routing Engine.
