Iosxrv-k9-demo-5.2.2.ova <COMPLETE ⇒>

The iosxrv-k9-demo-5.2.2.ova is a virtual appliance file for the Cisco IOS XRv Router, a virtualized platform designed to run the 32-bit Cisco IOS XR software on the QNX microkernel. As a "demo" version, it is specifically intended for training, familiarization, and early field trials (EFT) of control plane features. Core Technical Specifications

This specific version (5.2.2) is built for simulation environments like EVE-NG, GNS3, or direct deployment on VMware ESXi. Virtual CPU (vCPU): Requires a minimum of 1 vCPU.

Memory (vRAM): Requires 3072 MB (3GB) of RAM to function correctly.

Architecture: Runs 32-bit IOS XR on a QNX microkernel, appearing to the software as an x86-based machine.

Interfaces: Supports up to 128 interfaces, though typical virtual deployments use a smaller subset. Interface 0 is reserved for Management Ethernet. Deployment & Use Cases iosxrv-k9-demo-5.2.2.ova

The OVA format is standard for VMware platforms but can be converted for other hypervisors.

Direct Import: Can be imported into VMware Fusion or Workstation via File -> Import.

EVE-NG Integration: To use this file in EVE-NG, you must uncompress the OVA to extract the .vmdk file and then convert it to .qcow2 format using the qemu-img tool.

Initial Setup: Default credentials are often admin with no password. It follows a "two-stage" configuration process, meaning changes must be explicitly committed to take effect. Demo Restrictions Cisco XRv - - EVE-NG The iosxrv-k9-demo-5

9. Security Considerations for Lab VMs

Because the k9 crypto feature is present, treat this VM with the same baseline security as a physical router, even in a lab:

Change default credentials immediately. Even in an isolated lab, cisco/cisco is the first brute-force attempt.
Do not bridge the VM directly to an untrusted network (e.g., internet). IOS XR 5.2.2 has older SSL/TLS stacks and is not hardened for external exposure.
Use ACLs on the management interface even if you are behind NAT.

Technical Requirements for the OVA

Simply downloading the iosxrv-k9-demo-5.2.2.ova is not enough; you must ensure your virtualization host meets the requirements. IOS XR is not a lightweight operating system. It is a real-time, distributed OS that expects certain resources.

Important Note: IOS XR is very sensitive to clock latency. If you overcommit CPU resources on your hypervisor, you may experience "CPU Hog" messages or control plane instability. Always reserve at least 1 dedicated vCPU core for the XRv control VM.

Supported Virtual NICs:

The demo OVA is pre-configured with VMXNET3 adapters. Ensure your hypervisor supports paravirtualized network drivers for performance. Do not use E1000 unless you are prepared to modify the OVF.

10. Where to Go Next: Moving to Modern IOS XR

Version 5.2.2 is a fantastic starting point, but Cisco has evolved. If you master the iosxrv-k9-demo-5.2.2.ova, consider moving to:

IOS XRv 9000 (6.x, 7.x) – Supports 100 Gbps virtual line cards, SRv6, and full 5G transport features.
Cisco Modeling Labs (CML) 2.0 – Includes modern XRv images with Smart Licensing built-in.
Containerized XRv (XRv9k on Docker) – A lightweight version for CI/CD pipelines.

The CLI structure, commit model, and config hierarchy you learn on iosxrv-k9-demo-5.2.2.ova translate directly to these newer platforms.

❌ No data plane (limited forwarding)

This is a “demo” version – no real throughput. Traffic forwarding is simulated at very low rates.
Not suitable for performance testing or production-like traffic.

2. Data Plane Performance Limitations

The XRv is a control plane virtual router. It uses the host CPU for packet forwarding, meaning it cannot achieve line-rate forwarding (e.g., 10Gbps). Expect a few hundred Mbps at best with simple routing.

Solution: Use the XRv for control plane testing (BGP route propagation, policy) or low-throughput data plane tests. For high-performance data plane, consider the IOS XRv 9000 or physical hardware.

1. Decoding the Filename: `iosxrv-k9-demo-5.2.2.ova`

Before diving into deployment, let’s deconstruct the filename. Each segment provides vital information about the software’s purpose and limitations.

iosxrv : This stands for IOS XR Virtual. Unlike classic IOS (used on enterprise routers) or IOS XE (used on Catalyst/ASR1K), IOS XR is a separate operating system designed for high-end, carrier-grade platforms like the ASR 9000 and NCS 6000. The "Virtual" designation means this software image runs on standard x86 hardware (servers, laptops, or cloud instances) rather than dedicated Cisco silicon.
k9 : This denotes that the image includes strong cryptography (crypto) . In Cisco nomenclature, k8 (weak crypto) or k9 (strong crypto—3DES, AES, SSH, IPsec) indicates encryption capabilities. For modern labs, k9 is essential for VPN testing, secure management, and SSH access.
demo : This is the most critical suffix for users. The "demo" image is a pre-built, limited-purpose virtual machine supplied by Cisco for evaluation and learning. It comes with restrictions compared to a production IOS XRv image (e.g., a maximum interface count, lower throughput, or a reduced feature set). However, for learning BGP, OSPF, IS-IS, MPLS-TE, or segment routing, the "demo" version is more than sufficient.
5.2.2 : This is the software version of IOS XR. IOS XR version 5.2.2 was released in the 2015–2016 timeframe. While not the latest (Cisco has since released 6.x, 7.x, and 24.x), 5.2.2 remains popular for legacy labs, migration training, and environments testing feature parity with physical ASR 9000 series routers running similar trains.
.ova : Open Virtual Appliance is a compressed tar archive containing VM disk images (VMDK), manifest, and metadata (OVF). The OVA format is compatible with VMware ESXi, VMware Workstation, Fusion, VirtualBox (via import), and some open-source hypervisors.
