Each system includes at least one RP that performs a variety of functions
including the following:
Downloads the Cisco IOS software to all installed line cards at power-on.
•
Processes the network routing protocols and distributes updates to the Cisco
•
Express Forwarding (CEF) tables on the line cards.
Communicates with the line cards, either through the switch fabric or the
•
maintenance bus (MBus):
The switch fabric connection is the main data path for distributing
–
routing tables, as well as packets passed, between the RP and the line
cards.
The MBus connection allows the RP to download a system bootstrap
–
image, collect or load diagnostic information, and perform general,
internal system maintenance operations.
The GRP uses an IDT R5000 Reduced Instruction Set Computing (RISC) CPU
that runs at an external bus clock speed of 100 MHz and has an internal clock
speed of 200 MHz.
Figure 1-9 identifies the connectors and LEDs on the GRP front panel.
