This is a separate, accompanying QCOW2 image (often labeled vqfx-pfe-... ). It emulates the physical switching ASIC, managing data-plane packet transmission and port states.

To get this specific image working, you typically need its counterpart, the PFE (Packet Forwarding Engine) Name the template vQFX-RE-20
: Version 20.2R1.10 of Junos OS. (Note: Due to a known packaging quirk on the Juniper portal, many downloaded 20.2 images actually report as 19.4R1 internally during standard boots, but follow the same operational procedures).

The 20.2R1.10 Junos image can be intensive during initialization, sometimes throwing CPU lockup warnings on the console.
vQFX is the go‑to platform for building and testing , widely used in modern data centers. The juniper-evpn-vxlan-lab GitHub repository demonstrates an EVPN‑VXLAN fabric deployed in EVE‑NG, featuring eBGP underlay, iBGP EVPN overlay, VLAN‑to‑VNI mapping, and Anycast IRB gateways.
