: Because it is a demo, it is significantly throttled in terms of traffic throughput, often limited to around 200 Kbps.

The iosxrvk9demo-6.1.3.qcow2 is a pre-packaged QEMU Copy On Write (qcow2) image containing the Cisco IOS XR operating system, version 6.1.3. It is designed to run in a virtualized environment, offering the control plane capabilities of a high-end Cisco IOS XR router (such as the ASR 9000 or NCS series) without requiring physical hardware. Key Characteristics:

Notice the separating tokens. Your keyword iosxrvk9demo613qcow2 has no separators except the final dot. This violates several naming best practices:

The demo designation in the filename carries important legal and functional implications.

In the world of network engineering, file naming conventions are critical. They tell you the platform, the feature set, the version, the purpose, and the format. When confronted with a string like iosxrvk9demo613qcow2 , it is tempting to assume it is a downloadable file from Cisco. In reality, it appears to be a combined into one non-standard string.

You should change these credentials immediately after first boot. The existence of hard-coded users means anyone with access to the demo image’s documentation could potentially access your lab router if you expose management interfaces to untrusted networks. : Because it is a demo, it is

After the command runs, the VM will start and boot into the IOS XR bootloader, then proceed to the CLI prompt.

While newer versions of IOS XR are available, version 6.1.3 remains popular for several reasons:
