Overview of the Cisco 12008

A Cisco 12008 that is configured for full redundancy contains the following cards in the upper card cage:

Two RPs

Two CSCs

As many as six Cisco 12000 series line cards of any type and any combination

The following sections briefly describe the cards that you can use to populate the upper card cage.

Gigabit Route Processor

Each Cisco 12008 GSR has one main system (or route) processor. The route processor (RP) processes the network routing protocols and distributes updates to the Cisco Express Forwarding (CEF) tables on the line cards. The RP also performs general maintenance functions, such as diagnostics, console support, and line card monitoring.

Two types of RPs are available for the Cisco 12008 GSR:

Gigabit Route Processor (GRP)

Performance Route Processor (PRP)

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, redundant RP, it must be of the same type as the primary RP.

This section describes the GRP and includes the following information:

Memory components

System status LEDs

Soft reset switch

Personal Computer Memory Card Industry Association (PCMCIA) slots, which are used to transmit data to or from Flash memory cards
