Out-of-band management is typically handled via the em0 interface. Guide: Importing Juniper vMX and vQFX into CML2.4
: Minimum 4 (fxp0 for management, em0/em1 for internal PFE connection, and remaining for data bridging) Console Device : Telnet vQFX PFE (Companion Image) vCPU : 1 RAM : 2048 MB (2 GB)
Understanding the intricacies of this specific image, how it communicates with its counterpart, and how to properly configure it within virtual labs is essential for automated network testing and validation. 1. Deconstructing the File Name
: Verify the md5sum/sha256sum of your .qcow2 file to ensure it was downloaded correctly. vqfx202r110reqemuqcow2
file changed that. It allows an engineer to run a full-featured instance of Junos OS on a standard laptop or a cloud server. By using this image in tools like GNS3, EVE-NG, or Containerlab , you can build a massive data center topology virtually. 3. The Control Plane vs. The Data Plane This specific file is the RE (Routing Engine)
5 GB of free disk space per instance (QCOW2 thin-provisioning keeps initial sizes low, around 1 GB to 2 GB). Software Requirements A Linux-based host running KVM/QEMU .
A separate image (often designated pfe.qcow2 ) handles the data plane, forwarding packets between interfaces based on instructions from the RE. Out-of-band management is typically handled via the em0
disk image for the Juniper vQFX10000, a virtualized version of Juniper's high-performance data center switch. This specific version (20.2R1.10) is frequently used in network simulation environments like GNS3, EVE-NG, and Cisco Modeling Labs (CML). Cisco Learning Network 🛠️ Deployment Requirements To run a functional vQFX switch, you typically need virtual machines working in tandem: Routing Engine (RE): The control plane (manages Junos OS and configuration). Packet Forwarding Engine (PFE): The data plane (handles traffic forwarding). RE Hardware Specs (per node) 1024 MB (minimum) to 2048 MB. 1–2 vCPUs. QCOW2 (optimized for QEMU/KVM). brezular.com 🚀 Installation & Setup
: Indicates Release 1 of that specific version. This suggests it is the first candidate or official release of the 202 build.

virtual switch. This virtual appliance allows network engineers to simulate a high-performance Juniper QFX Series data center switch in virtual environments like Containerlab File Name Breakdown
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.
Using the Juniper vQFX RE image, you can build a full (Spine-and-Leaf). A standard lab setup might look like this:
