Troubleshooting the Route Processor Subsystem
The router processor subsystem consists of the route processor located on the RSP card. The RSP and
the line cards each have the same onboard CPU serving as the main processor. The Controller Area
Network (CAN) microcontroller processor monitors the environment and controls the onboard
DC-to-DC converters.
Note A minimally configured router must have an RSP/RP installed in RSP slot 0 or RP slot 0 of the card cage
to operate. If the router is equipped with a redundant RSP/RP, the redundant RSP/RP must be installed
in RSP slot 1 or RP slot 1 of the card cage.

Route Processor Overview

The CPU on the RSP/RP card provides chassis control and management, boot media functionality,
telecom timing and precision clock synchronization, communication to the line cards through the
backplane Ethernet network, and power control through the CAN bus. In addition, the CPU on the
RSP/RP card also runs the routing protocols.
The RP2 card has more processing power than the earlier RP. It also doubles the amount of storage and
supported memory as well as the memory bandwidth. This provides the path to scale the number of
routes up in this generation. In addition the internal control plane bandwidth has been scaled up to allow
better control of the linecards as the network bandwidth increases. Figure 4-8 identifies the ports and
LEDs on the RP card front panel. Figure4-9 identifies the ports and LEDs on the RP2 card front panel.
