The RE and PFE must be interconnected in your virtual workspace using dedicated backplane links to function as a unified virtual switch. Key Technical Specifications gns3-registry/appliances/juniper-vqfx-re.gns3a at master

Juniper typically provides these images via the official Juniper Download site (requires a support contract) or a Juniper vLabs trial. If you have access, search for "vQFX 20.2R1.10."

: To enable actual traffic flow, the RE must be properly linked to the PFE VM via internal virtual bridges. Juniper Elevate Community Usage Use Cases Lab Testing : Ideal for testing VXLAN/EVPN

Refined telemetry capabilities for modern network monitoring.

Validate 3-stage or 5-stage Clos topologies using CRB (Centrally Routed Bridging) or ERB (Edge Routed Bridging) configurations before rolling variations out to real QFX5110 or QFX5120 switches. Vqfx-20.2r1.10-re-qemu.qcow2

Once you start the node in your simulator:

This file is a specific disk image for the Juniper vQFX (Virtual QFX) network switch, running Junos OS version 20.2R1.10 . It is designed to be used with the vPFE (Virtual Packet Forwarding Engine) image to create a complete, functional virtual switch for lab environments, typically using EVE-NG or GNS3.

The RE virtual machine is relatively lightweight, typically requiring at least 1024 MB of RAM and a single vCPU.

Licensing and legality

The Vqfx-20.2r1.10-re-qemu.qcow2 file is far more than a generic disk image. It is the virtualized brain (the Routing Engine) of a Juniper QFX10000 switch, packaged specifically for the QEMU hypervisor. Mastering the use of this image across platforms like GNS3, EVE-NG, and Containerlab provides network professionals with an unparalleled ability to learn, experiment, and automate.

Before initiating deployment, verify that your hypervisor host (EVE-NG bare-metal, GNS3 VM, or local Linux machine) meets the resource allocations required for stable operation. Resource Allocations per Node Minimum RAM Recommended RAM Disk Space ( 20.2r1.10 ) ~5 GB (Sparse) vQFX PFE ~2 GB (Sparse) Juniper Elevate Community Usage Use Cases Lab Testing

The versatility of the vQFX image makes it a powerful tool across many network emulation platforms.

This denotes . The QFX series is Juniper’s line of high-performance data center switches (e.g., QFX5100, QFX5110, QFX10000). The "v" indicates it is the virtualized version of this switching platform. Unlike a virtual MX (vMX) which acts as a router, the vQFX is designed to simulate a top-of-rack (ToR) data center switch.
