Note: This is an older release (6.1.3 was End-of-Life / End-of-Support several years ago). While stable for legacy labs, it lacks newer features found in IOS XR 7.x and 24.x (such as Smart Licensing, newer YANG models, and containerized apps).

iosxrv: Indicates the IOS XRv platform, which is the virtualized version of Cisco's IOS XR operating system typically used in service provider environments.

k9: Denotes the "K9" crypto payload, meaning the image includes support for strong encryption (like SSH or IPsec).

demo: Specifies that this is a demonstration or evaluation version. These are often used for lab environments, testing, or learning purposes and typically have throughput limitations.

613: Represents the software version, in this case, Cisco IOS XR Release 6.1.3.

qcow2: The file extension for QEMU Copy-On-Write. This is the standard disk format used by virtual machine monitors like KVM, QEMU, and GNS3. Common Use Cases

This specific file is most frequently used by network engineers and students within network simulation tools.

GNS3 / EVE-NG: It is often imported into these platforms to build virtual labs.

Cisco Modeling Labs (CML): While CML often uses newer versions, this older demo image is a common community resource for lightweight testing.

Learning BGP/MPLS: Because IOS XR is a modular, high-end operating system, this image allows users to practice service provider technologies like BGP, MPLS, and Segment Routing without needing $50,000+ hardware. Resource Requirements

To run this image effectively in a virtual environment, you typically need to allocate:

RAM: At least 3GB to 4GB (though it can sometimes boot with 2GB). CPU: 1 vCPU is usually sufficient for demo labs.

It looks like you’ve provided a string: iosxrvk9demo613qcow2

Understanding the iosxrv-k9-demo-6.1.3.qcow2 Virtual Router Image

The keyword iosxrvk9demo613qcow2 refers to a specific virtual machine disk image: the Cisco IOS XRv 6.1.3 Demo K9

in QCOW2 format. This image is a cornerstone for network engineers and students who need to simulate the Cisco IOS XR operating system—the high-end software typically found on carrier-grade routers like the ASR 9000 or NCS series. What is IOS XRv?

Cisco IOS XRv is a virtualized version of the IOS XR operating system designed to run on standard x86 hardware. Unlike the "classic" IOS software, IOS XR is a 32-bit (or 64-bit in newer versions) microkernel-based OS that offers high availability and modularity.

The demo version of this image (iosxrv-k9-demo-6.1.3.qcow2) is intended for education, familiarization, and basic configuration testing. It typically includes:

Full Control Plane: Support for BGP, OSPF, ISIS, and MPLS configurations.

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

QCOW2 Format: A "Copy On Write" format optimized for QEMU/KVM hypervisors, making it natively compatible with tools like GNS3 and EVE-NG. Technical Specifications for Version 6.1.3

The 6.1.3 release of IOS XRv is a widely used stable demo image for lab environments. Based on GNS3 community documentation, the file has the following characteristics: Specification Filename iosxrv-k9-demo-6.1.3.qcow2 File Size MD5 Hash 1693b5d22a398587dd0fed2877d8dfac Recommended RAM 3072 MB (3 GB) Hypervisor Using the Image in Lab Environments

This image is a staple for building complex network topologies without needing expensive hardware. 1. EVE-NG Integration

To use this image in EVE-NG, you must follow a specific directory structure:

Create a folder named xrv-k9-6.1.3 (or similar) in /opt/unetlab/addons/qemu/. Rename the file to hda.qcow2 once inside that directory.

Run the "fix permissions" command: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions. 2. GNS3 Deployment IOS XRv 9000 - Cisco Modeling Labs v2.9 - Cisco DevNet Note: This is an older release (6

router, typically used for network simulation and lab testing. This specific version (6.1.3) is an older "classic" 32-bit release often found in lab environments like GNS3, EVE-NG, or Cisco Modeling Labs (CML). 1. Product Overview Platform: Cisco IOS XRv (Virtual Router).

Role: Designed to provide traditional Provider Edge (PE) services and Route Reflector (RR) capabilities in a virtualized environment.

Architecture: The "classic" IOS XRv is a 32-bit virtualized version of the IOS XR operating system used on Cisco carrier-grade hardware like the ASR 9000.

Demo Mode: The "demo" designation indicates that the image runs with performance limitations (e.g., throughput capped at ~200 Kbps) until a valid license is applied. Where can I find the IOS XRv 9000 image?

iosxrv-k9-demo-6.1.3.qcow2 is a virtual disk image for the Cisco IOS XRv router, specifically version 6.1.3 of the "demo" release. This image allows network engineers to simulate a virtual machine (VM) running the 32-bit IOS XR operating system for education, configuration staging, and network modeling. Technical Overview Since the filename includes demo , boot the

Platform Architecture: Runs the 32-bit Cisco IOS XR "classic" software with a QNX microkernel.

Resource Requirements: Typically requires 3072 MB (3 GB) of RAM.

Virtualization Support: Compatible with QEMU/KVM environments and commonly used in network emulation tools like GNS3, EVE-NG, and Cisco Modeling Labs (CML). Common Deployment Scenarios

Vagrant & Libvirt: Users often convert this .qcow2 image into a Vagrant box using scripts like those found in the vagrant-libvirt repository for automated local lab deployment.

Virtual Machine Conversion: If starting with an .ova or .vmdk file, it can be converted to .qcow2 for use in KVM-based hypervisors.

Interface Mapping: The management interface is typically MgmtEth0/0/CPU0/0, while data interfaces follow the Gi0/0/0/n format. Current Status and Limitations

Deprecated: IOS XRv is now considered a legacy platform and has reached its end-of-support date.

Feature Gaps: Because it is an older 32-bit demo image, it lacks support for modern features like Segment Routing (SR) Policies or Flex Algo.

Successor: For production use cases or modern feature evaluation, Cisco recommends using IOS XRv 9000, which runs the 64-bit IOS XR software.

Note on Usage: When first booting, the default username is often admin without a password, though users are typically prompted to set credentials immediately. Remember that IOS XR uses a two-stage configuration process—you must explicitly use the commit command for changes to take effect.
