The first interface ( em0 / fxp0 in Junos) maps to your management network.
When building high-fidelity data center simulations, staging EVPN-VXLAN fabrics, or validating automated Junos scripts, finding a reliable virtual switch image is critical. The Juniper vQFX10000
Unlike straightforward virtual machines, the vQFX relies on a to mimic bare-metal hardware. To form a completely functional node, you must orchestrate two separate QEMU images simultaneously:
This specific file ( vqfx-20.2R1.10-re-qemu.qcow2 ) is available to authorized Juniper customers via the Juniper Networks Support Portal (Software Download Center). vqfx202r110reqemuqcow2 work
Physical Juniper QFX10000 switches rely on independent control planes (the Routing Engine) and high-speed switching ASICs (the Packet Forwarding Engine). The vqfx-20.2R1.10-re-qemu.qcow2 image mimics this separation digitally:
If you are setting this up right now, let me know you are using (like EVE-NG, GNS3, or pure KVM). I can give you the exact network mapping topology or node templates needed to link your RE and PFE seamlessly. Share public link
The console flickered. Juniper’s loader chugged. Then—green text. The first interface ( em0 / fxp0 in
The qcow2 format makes this image highly compatible with modern network emulation platforms like , EVE-NG , or raw QEMU/KVM setups. 1. Importing into EVE-NG
The vQFX splits control (RE) and forwarding (PFE). Check:
Setting up the vQFX image in EVE-NG involves importing both the RE and PFE images correctly. The process is well-documented within the EVE-NG community. To form a completely functional node, you must
The following flowchart illustrates the complete vQFX deployment process in EVE-NG:

"Step one: clone," he whispered, typing:
Let’s break it down:
