Cisco IOS XRv Router Overview
The Cisco IOS XRv Router is a Virtual Machine (VM) based platform running 32-bit IOS XR software with the QNX microkernel. This VM contains a single route processor (RP) with control plane functionality, and line card (LC) network interfaces with their associated functionality. It is a representation of the IOS XR software and operating system, including manageability, control plane features, routing and forwarding functionality. The Cisco IOS XRv Router is not an emulation of any physical router or hardware component.
For more information on installing and configuring the Cisco IOS XRv Router, refer to the Cisco XR Virtual Router Installation and Configuration Guide.
