Product Line(s)

The PRP uses the following types of memory. :

•Route memory—Synchronous dynamic random access memory (SDRAM) enables an onboard processor to run Cisco IOS software and store network routing tables. You can configure route memory from the factory default of 512 MB to the maximum configuration of 2 GB.

•PRP onboard Flash memory—Single in-line memory module (SIMM) stores the boot helper software to boot the router when a valid Cisco IOS software image is not available on a Flash disk or a linear Flash memory card.

•PRP Flash disk—A convenient, offline medium for storing a copy of the default Cisco IOS software image. The Flash disk can be inserted into either of the two Flash disk slots in the PRP, so that you can load router software into PRP main memory.

•PRP erasable programmable read-only memory (EPROM)—Contains a ROM monitor that enables you to boot the default Cisco IOS software image from a Flash disk if the Flash memory SIMM does not contain a boot helper image.

•PRP Random access memory—Nonvolatile random-access memory (NVRAM) provides a stable medium for storing the router's configuration files, the environmental monitoring logs, and the contents of the router's virtual configuration register.
