The RE and PFE communicate over an internal virtual bridge network. Without the PFE, the RE will boot and allow you to configure Junos, but the network interfaces will remain down or fail to pass traffic. System Requirements for Deployment
: Indicates the Virtual QFX switching platform, which runs Juniper’s Junos operating system optimized for data center leaf-and-spine simulations.
Virtual Chassis—specifically the Routing Engine (RE) component—packaged for the QEMU emulator. vqfx202r110reqemuqcow2
In essence, this is a virtual disk image that contains the Routing Engine component of a Juniper QFX switch, running Junos OS version 20.2R1.10, packaged for QEMU hypervisors in the efficient qcow2 disk format.
Validate the integrity of the downloaded file using the QEMU disk utility: qemu-img info vqfx202r110reqemuqcow2 Use code with caution.

| | Cons | | :--- | :--- | | High Fidelity: Excellent for learning EVPN-VXLAN and Data Center fabrics. | Resource Heavy: Consumes significant RAM/CPU per node. | | Modern Code: Version 20.2 supports newer Junos features and ELS syntax. | Slow Boot: Takes 3-6 minutes to fully boot and pass traffic. | | ELS Support: Matches the syntax used on modern physical QFX devices. | Fragile: Prone to corruption if not shut down gracefully. | | Free Labbing: Allows testing expensive hardware architectures for free. | Data Plane Lag: The virtual PFE can sometimes lag behind the control plane. |
Intel VT-x or AMD-V virtualization extensions enabled in the BIOS/UEFI.
