Vqfx202r110reqemuqcow2 Top [verified] -
The substring reqemu is a clear indicator that this image is specifically tailored for . Unlike a physical switch, the vQFX’s Routing Engine (RE) and PFE (Packet Forwarding Engine) are emulated via QEMU’s TCG (Tiny Code Generator) or KVM acceleration. The req might also imply that the image expects certain hardware virtualization extensions (Intel VT-x / AMD-V) to be present.
This is the vqfx202r110reqemuqcow2 image. It runs the Junos operating system, manages the configuration, runs routing protocols (like BGP, OSPF, and EVPN-VXLAN), and provides the CLI interface. It requires very low processing power. 2. The Packet Forwarding Engine (PFE)
Alternatively, at the Junos CLI:
. This file is more than just data; it represents a sophisticated Routing Engine

This image, usually named something like vqfx-20.2R1.10-re-qemu.qcow2 , contains the control plane of the switch. It runs the Junos OS and handles routing protocols, management, and configuration. It is the brain of the virtual switch.

Whether you are using GNS3 or EVE-NG, the core logic remains the same: the RE manages the control plane, while the PFE handles the data plane. 1. Image Requirements
The 20.1R1 release was a significant milestone for vQFX, offering mature support for EVPN-VXLAN fabrics. When deploying this image, you generally use one of two topologies: This is the vqfx202r110reqemuqcow2 image
