: While it supports most control plane features (BGP, OSPF, ISIS), complex data plane features like certain L2VPN/MPLS forwarding scenarios may not work as expected. Performance & Usability Review IOS XRv - Cisco Modeling Labs v2.9

In its day, this image was not a direct public download. Obtaining iosxrv-k9-demo-6.1.3.qcow2 typically required a subscription to . Users would log into the Cisco Software Download portal and, under their VIRL subscription, download the image for use in their local environments.

While newer versions of IOS XR (like XRv 9000) exist, version 6.1.3 remains popular because it is relatively "lightweight" compared to the 16GB+ RAM requirements of the 9000 series. It is perfect for complex BGP route policy testing or prefix-set labbing where you need to run 5-10 routers on a single laptop.

The file is a virtual disk image for the Cisco IOS XRv Router, a platform designed to run the IOS XR operating system as a virtual machine. This specific image is a "demo" version of release 6.1.3, typically used by network engineers and students for training, configuration staging, and network modeling in emulation environments like GNS3 , EVE-NG , or Cisco Modeling Labs (CML). Architecture and Technical Requirements

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.
