Use virtio-net-pci for the network interfaces to get the best throughput and lowest latency between virtual nodes.
Unlike older versions, 20.2R1.10 supports advanced data center protocols. If you are building a Spine-and-Leaf architecture in a lab, this image handles the control plane requirements for VXLAN overlays and BGP underlays flawlessly.
Before you boot this image, ensure your hypervisor (EVE-NG, GNS3, or PNETLab) meets these specs: Intel VT-x or AMD-V support is mandatory. vqfx202r110reqemuqcow2 top
While it requires significant RAM (usually 2GB to 4GB per RE), it scales better than trying to run full physical hardware simulations. Key Requirements for Running vQFX202R110
Remember, the vQFX is a dual-image system. You cannot move traffic with just the RE file. You must pair it with a vQFX-PFE (Packet Forwarding Engine) image. The RE handles the CLI and routing protocols, while the PFE handles the actual "cabling" and data transit. Best Practices for Setup Use virtio-net-pci for the network interfaces to get
Ensure the folder is named correctly (e.g., vqfxre-20.2R1.10 ) so the platform recognizes the template.
Allocate at least 2048MB (2GB) to the RE. If you are doing heavy routing, 4096MB is safer. Before you boot this image, ensure your hypervisor
To understand the file name, we have to break down its components:
