This process is essential for running the image on VMware Fusion, Workstation, or ESXi.

To run effectively, the image generally requires at least 3 GB of RAM and access to a KVM-enabled environment.

image remains a staple for CCNA/CCNP Service Provider candidates. Whether you are automating your lab with Vagrant or building complex topologies in GNS3, this image offers a reliable way to master the IOS XR CLI without the need for $20,000 hardware. configuration snippet for BGP or OSPF to get your lab started? Iosxrv-k9-demo-6.1.3.qcow2

Unlike the commercial XRv, this demo image has reduced forwarding performance. Do not use for throughput testing >100 Mbps.

: This behavior is normal for the demo image during bootup. Once the control plane fully initializes, CPU usage on the host machine typically stabilizes.

: Label Distribution Protocol (LDP), RSVP-TE (Traffic Engineering), and Segment Routing (SR). This process is essential for running the image

You will not be able to create a new user with any of these hard-coded names, and attempting to do so during the admin setup will result in an error. The workaround is to choose a username not on this list for your administrative account.

Known Limitations of the Demo Image

This image is designed for and learning , not production. Whether you are automating your lab with Vagrant

Running service provider operating systems in a virtual environment requires adequate hardware allocation. If you do not assign enough resources to the image, the boot process will hang, loop, or crash.

Minimal qemu launch (example):

| Feature | Demo Status | |---------|--------------| | Throughput | Limited to ~100k pps | | Uptime | Resets every 60 minutes | | Interfaces | 2–3 usable virtio interfaces | | Crypto (IPsec) | Present but slow | | XR HA (NSR) | Disabled |

: This indicates a demonstration or evaluation version. It functions with full software capabilities but features built-in throughput limits (typically throttled to low speeds like 15 Kbps to 2 Mbps depending on the exact sub-version) to prevent production deployment without a commercial license.
