The PRP-2 is available as Product Number PRP-2 or PRP-2=, which includes one PRP with 1 G of synchronous dynamic random-access memory (SDRAM) and one 64-MB advanced technology attachment (ATA) Flash disk. A redundant PRP (Product Number PRP-2/R) is also available.

PRP Functions

The PRP-1 for the Cisco 12000 Series Router includes the following primary functions:

Loading Cisco IOS software on all installed line cards at power up

Providing a console (terminal) port for router configuration

Providing an auxiliary port for other external equipment (such as modems)

Providing two IEEE 802.3, 10/100-megabits-per-second (Mbps) Ethernet ports for Telnet functionality

Running routing protocols

Building and distributing routing tables to line cards

Providing general system maintenance functions

Communicating with line cards either through the switch fabric or through the maintenance bus (MBus). The MBus connection allows the PRP to download a system bootstrap image, collect or load diagnostic information, and perform general, internal system maintenance operations. The switch fabric connection is the main data path for routing table distribution as well as for packets that are sent between line cards and the PRP.
