Prerequisites for Configuration

You must be in a user group associated with a task group that includes the proper task IDs. The command
reference guides include the task IDs required for each command. If you suspect user group assignment is
preventing you from using a command, contact your AAA administrator for assistance.
Before configuring the nV Edge system, you must have these hardware and software installed in your chassis:
• Hardware: Cisco ASR 9000 Series SPA Interface Processor-700 and Cisco ASR 9000 Enhanced Ethernet
• Software: Cisco IOS XR Software Release 4.2.x or later on Cisco ASR 9000 Series Router.
For more information on hardware requirements, see Cisco ASR 9000 Series Aggregation Services Router
Hardware Installation Guide.

Overview of Cisco ASR 9000 nV Edge Architecture

A Cisco ASR 9000 Series nV Edge system consists of two Cisco ASR 9000 Series Router chassis that are
combined to form a single logical switching or routing entity. You can operate two Cisco ASR 9000 Series
Router platforms as a single virtual Cisco ASR 9000 Series system. Effectively, they can logically link two
physical chassis with a shared control plane, as if the chassis were two route switch processors (RSPs) within
a single chassis as shown in the figure. The blue lines on top shows the internal eobc interconnection and the
red lines at the bottom show the data plane interconnection.
