Vqfx-20.2r1.10-re-qemu.qcow2

To allocate resources properly in your hypervisor or simulation host machine, configure your VM template using these foundational baselines: Install Juniper vQFX 19.4R1.10 on GNS3

When you boot this QCOW2 file, you get the Routing Engine . In a real QFX, the RE sends instructions to the PFE (Packet Forwarding Engine) via an internal link (typically em1 or fxp0 ).

Troubleshooting tips

The vQFX requires a specific internal connection to bridge the control plane (RE) and data plane (PFE). Management Port: Connect the first interface ( ) of the RE to your management network or admin VLAN. Internal Link: Connect the second interface ( ) of the RE directly to the second interface ( ) of the PFE. Data Ports: Vqfx-20.2r1.10-re-qemu.qcow2

The two virtual machines must be connected via their em1 interfaces to form a single functional switch unit. Known Issues & Version Discrepancies

: This is the Control Plane (RE) of the virtual switch. In a vQFX setup, this image handles the Junos OS, routing protocols, and management. To allocate resources properly in your hypervisor or

Ensure you have both the RE and PFE images.

Nested virtualization (VT-x/AMD-V) must be enabled on your physical host machine.

If you are looking for documentation or a "paper" on how to deploy or use this specific image, here are the key details you need to know: Overview of the Image Management Port: Connect the first interface ( )

Use this image for JunOS CLI practice , routing protocol labs , and automation testing . For EVPN/VXLAN data center work, prefer vJunOS-switch 22.x or later.

The file is a virtual disk image representing the Routing Engine (RE) component of Juniper Networks' vQFX10000 virtual switch . This specific image is based on Junos OS 20.2R1 and is designed to run in a QEMU/KVM hypervisor environment, commonly used for high-fidelity network simulation in labs like GNS3 or EVE-NG .
