The file is the virtual disk image for the Routing Engine (RE) of Juniper Networks' vQFX10000 virtual switch. Designed to emulate the QFX10000 series data center switch, this specific image allows network engineers to simulate high-performance Juniper QFX fabrics within virtualized lab environments like GNS3, EVE-NG, or Cisco Modeling Labs (CML). Role of the RE Image
Eve-NG is one of the most popular platforms for hosting vQFX topologies. Follow these precise steps to format and mount the image. Step 1: Create the Directory Structure
Handles actual data plane traffic forwarding between lab interfaces.
Unlike some virtual routers that run inside a single virtual machine, the vQFX relies on a dual-VM architecture to accurately simulate hardware switches. 1. The Routing Engine (RE) VM Vqfx-20.2r1.10-re-qemu.qcow2
: The RE and PFE must be connected internally via their dedicated em1 interface for the two to communicate properly. This internal link is not available for data-plane traffic.
The filename breaks down into highly specific technical designations:
mimics physical enterprise switching hardware by splitting its software architecture into two separate virtual machines: The file is the virtual disk image for
Using an SFTP client (like WinSCP or FileZilla), upload your Vqfx-20.2r1.10-re-qemu.qcow2 file into the folder you just created.
Refined telemetry capabilities for modern network monitoring.
This image is a staple for network engineers using emulation platforms. It allows for building complex data center topologies (like Leaf-Spine architectures) without needing physical hardware that costs thousands of dollars. 2. CI/CD and Automation Testing Follow these precise steps to format and mount the image
Nested virtualization (VT-x/AMD-V) must be enabled on your physical host machine.
: vQFX is efficient, but running many instances requires significant RAM and CPU.
