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 MX10003
host subsystem consists of two Routing and Control Boards, or RCBs. The RCB is an integrated board and
a single FRU that provides Routing Engine (RE) and Control Board (CB) functionality. The RE performs all
route-processing functions, whereas the CB performs chassis control and management plane functionality.
The RCB provides control plane functions. You can install one or two RCBs on the router. Each RCB
functions as a unit.
NOTE: Install two RCBs for redundant protection. If you install only one RCB, you can install it
in slot 0 or slot 1. By default, slot 0 functions as the master.
