: While it can run a full Internet routing table in theory, allocating only 3-4 GB of RAM will cause the virtual router to crash or drop BGP peers if flooded with millions of prefixes. Keep lab topologies focused and minimized. Conclusion
Preparing for CCIE Service Provider or Cisco Certified Specialist – Service Provider Routing certifications requires hands-on experience. This OVA allows you to build complex topologies (e.g., MPLS L3VPN, L2VPN, Segment Routing) on a single laptop.
Run the following command in the EVE-NG CLI: /opt/qemu/bin/qemu-img convert -f vmdk -O qcow2 iosxrv-demo.vmdk hda.qcow2 iosxrv-k9-demo-5.2.2.ova

Place the hda.qcow2 file inside the correctly named directory on your EVE-NG server (e.g., /opt/unetlab/addons/qemu/iosxrv-5.2.2/ ). Supported Features and Use Cases
: 3 GB to 4 GB (While 4 GB is recommended, it can often boot on 3 GB for basic routing labs). Storage : 2 GB to 4 GB of thin-provisioned disk space. Compatible Hypervisors and Virtual Environments This OVA allows you to build complex topologies (e
Demo images often have feature or uptime limitations and are intended for lab/demo use only — not for production. Crypto (k9) features present but governed by demo license terms.
Native deployment via "Deploy OVF Template."
Version 5.2.2 strikes a balance between stability and modern features. It supports:
The VM has been assigned less than 3 GB of RAM, or your CPU virtualization extensions (Intel VT-x or AMD-V) are disabled in the hardware BIOS.
