Backed by the vqfx-20.2R1.10-re-qemu.qcow2 file, this VM handles the control plane. It runs the Junos operating system, handles routing protocols (like BGP and OSPF), updates routing tables, and manages user CLI sessions.

Understanding how to deploy, patch, and manage this virtual asset is critical to building functional EVPN-VXLAN structures and data center fabrics in a sandbox environment. Architectural Breakdown of the vQFX Top Template

The RE and PFE must be connected via the EM1 interface to communicate. Common Issues and Fixes

This article unpacks every component of that keyword, providing a holistic guide for engineers looking to deploy, optimize, and monitor a Juniper vQFX series virtual switch on a QEMU/KVM hypervisor using the QCOW2 disk format. Backed by the vqfx-20

Emulates the data plane and switching ASICs (often labeled as cosim images running Wind River Linux).

Initial setups often include extensive default configurations that can conflict with lab topologies. You can enter the configuration mode and use delete from the top hierarchy, but you must ensure the em1 interface configuration is preserved to keep the RE and PFE linked. Architectural Breakdown of the vQFX Top Template :

This comprehensive guide breaks down the core architecture of the vQFX image, resolves a well-known version reporting anomaly, and provides step-by-step instructions for deploying it inside industry-standard network emulators like GNS3, EVE-NG, and Containerlab . Core Architecture: The Two-VM Split

: The specific Junos OS software release version (Version 20.2R1.10).

Remember, the vQFX is a dual-image system. You cannot move traffic with just the RE file. You must pair it with a vQFX-PFE (Packet Forwarding Engine) image. The RE handles the CLI and routing protocols, while the PFE handles the actual "cabling" and data transit. Best Practices for Setup
