For information about the line card that the Cisco 10008 router supports, see the Cisco 10000 Routers
Line Card Hardware Installation Guide, and for line card configuration information, see the
Cisco 10000 Series Router Line Card Configuration Guide.
Performance Routing Engine
The PRE is the central router and system controller (SC) for the Cisco 10008 router. It is responsible for
all Layer 2 and Layer 3 packet processing, as well as execution of routing protocols and management of
the system. The PRE consists of two main logical and physical cards:
•
•
The high performance forwarding engine in the PRE is Cisco's Parallel eXpress Forwarding (PXF)
application specific integrated circuit (ASIC). The two PXF ASICs on the PRE direct traffic to and from
the router line cards.
