Iosxrv-k9-demo-6.1.3.qcow2 May 2026

Cisco IOS XR is significantly different from standard IOS or IOS XE. It is a micro-kernel architecture designed for high-end Carrier Grade Routers (like the CRS-1, ASR 9000, and NCS 5500).

IOS XRv 6.1.3 sits at a sweet spot in history:

This article explains what this file is, where it comes from, its limitations, and how to use it effectively for Cisco learning and labbing. Iosxrv-k9-demo-6.1.3.qcow2

The filename itself is a treasure trove of metadata. Let’s break it down:

In summary, this file is a virtual hard disk for a Cisco IOS XRv router, version 6.1.3, with full encryption, a demo license, packaged for the QEMU/KVM hypervisor.

Version 6.1.3 demo lacks support for:

While newer images exist, iosxrv-k9-demo-6.1.3.qcow2 represents a golden era for network emulation. It offers the perfect balance of modern routing protocol support (Segment Routing, BGP-EVPN fundamentals) and lightweight performance.

For the CCIE candidate, the SD-WAN architect, or the network automation engineer—this single file unlocks the ability to build a carrier-grade service provider lab on a laptop. Respect its limitations (control plane only, demo feature set), master its deployment on EVE-NG or KVM, and you will have a lifelong lab environment ready to simulate MPLS, L3VPNs, and IS-IS topologies at zero hardware cost.

Next Steps for the Engineer:

The demo image is your gateway to the world of IOS-XR. Boot it, break it, rebuild it, and learn.

If you need a virtual router that actually forwards packets:

| Image | Forwarding | License | |-------|------------|---------| | vMX (Juniper) | Yes | Trial available | | XRv 9000v (full) | Yes | Requires Cisco service contract | | vSRX (Juniper) | Yes | Trial available | | FRRouting | Yes | Free/Open source | | Cisco CSR1000v | Yes | Trial license (60 days) | Cisco IOS XR is significantly different from standard

For pure IOS XR learning without forwarding, the demo image is fine.

[Client PC] --- [PE1 - XRv 6.1.3] --- [P1 - XRv 6.1.3] --- [PE2 - XRv 6.1.3] --- [Client PC2]
                 |                    |                     |
                 [ASBR1] ------------ [ASBR2] (E-BGP over IPv4)

You can easily spin this up in EVE-NG. Configure ISIS Level-2 only on core links, enable MPLS globally, and establish LDP or SR.
