format is optimized for QEMU-based environments, making it compatible with: Available via the Juniper vQFX RE appliance in the GNS3 Marketplace. Cisco CML: Can be imported using community node definitions. KVM/Libvirt:

Ensure you also have a matching or compatible vQFX PFE image placed in a folder starting with vqfxpfe- (e.g., /opt/unetlab/addons/qemu/vqfxpfe-20.2r1.10/virtioa.qcow2 ). Step 3.5: Interconnecting RE and PFE in the EVE-NG Topology Open your EVE-NG web UI topology canvas. Right-click, select , and add a Juniper vQFX RE node. Add a Juniper vQFX PFE node.

: If not already done, rename the file to virtioa.qcow2 (the standard required by EVE-NG for the RE). Vqfx-20.2r1.10-re-qemu.qcow2

: Stands for Virtual QFX, mirroring Juniper's premier data center switching platform.

Juniper provides vQFX free of charge to its customers and partners, making it a key tool for various purposes:

Note: Junos 20.2r1 and higher versions run a FreeBSD 11/12 underlying kernel, requiring slightly more memory headroom than older 15.1X releases. Mastering Network Virtualization: A Deep Dive into Vqfx-20

configurations and other data center fabric protocols before hardware deployment. Automation : Compatible with Containerlab for building automated network "spins". Educational

Mastering virtualized enterprise networking requires robust, reliable sandboxes, and the image is a cornerstone for engineers simulating Juniper Networks environments. Specifically, this QEMU copy-on-write ( .qcow2 ) file serves as the Routing Engine (RE) for the vQFX 10000

: Create a folder in /opt/unetlab/addons/qemu/ (e.g., vqfx-20.2R1.10 ). Step 3

Connect of the RE node to em1 of the PFE node. This forms the internal management and control plane link.

Unlike standard network emulators that wrap everything into one image, the vQFX splits the system into two distinct virtual machines. This architecture mirrors physical hardware mechanics:

A white paper or technical guide for the image would focus on its role as the Routing Engine (RE) component of Juniper's virtualized QFX10000 switch series. This image is designed for network emulation platforms like GNS3 and Containerlab to simulate complex Data Center (DC) fabrics. Technical Overview: Juniper vQFX 20.2R1.10

: With the split architecture, all configuration, management, and operational commands are issued exclusively on the RE. You can verify the PFE's operational status and that the data plane is online with the command:

Utilising the 20.2r1.10 version of Junos OS brings a wealth of enterprise routing and switching capabilities into your virtual lab. Some of the standout features include:
