Cisco Systems 12406 series, 12006 series Route Processor Types, Gigabit Route Processor, 1-16

Chapter 1 Product Overview

Route Processors

Route Processor Types

Two types of RPs are available for Cisco 12006 and Cisco 12406 routers, the Gigabit Route Processor (GRP), and the Performance Route Processor (PRP).

Each of these route processor types is reviewed in the following sections:

•Gigabit Route Processor, page 1-16

•Performance Route Processor, page 1-25

When not explicitly specified, this document uses the term route processor (RP) to indicate either the GRP or the PRP.

Note If you install a second RP for redundancy, the second RP must be of the same type as the primary RP.

Gigabit Route Processor

This section provides information about the GRP. The GRP front view is shown in Figure 1-4.

•RISC processor—IDT R5000 Reduced Instruction Set Computing (RISC) processor used for the CPU. The CPU runs at an external bus clock speed of 100 MHz and an internal clock speed of 200 MHz.

•DRAM—Up to 512 megabytes (MB) of parity-protected, extended data output (EDO) dynamic random-access memory (DRAM) on two

60-nanosecond (ns), dual in-line memory modules (DIMMs). 128 MB of DRAM is the minimum shipping configuration for the GRP.
