The virtualized counterpart, , combines the route processor (RP) and line card (LC) functionality into a single virtual machine (VM) footprint. The image version denoted by iosxrvk9demo613qcow2 is explicitly packaged as a demo/trial image intended for learning, sandbox staging, and configuration verification rather than production traffic forwarding. Understanding the Technical Anatomy of the File iosxrvk9demo613qcow2

The virtual version ( XRv ) consolidates the control plane (Route Processor) and data plane (Line Cards) into a single virtual machine image. The tag signifies a free trial or evaluation tier. It contains fully functional control plane features but enforces a data-plane throughput rate limit (typically 2 Mbps to 15 Mbps), making it perfect for labs but unusable for actual production traffic. Breaking Down the File Name: iosxrv-k9-demo-6.1.3.qcow2

: Denotes a free-tier or evaluation edition. It features an unlicensed data plane that enforces a strict rate limit on packet throughput (typically throttled to 250 Kbps or lower).
