Vqfx-20.2r1.10-re-qemu.qcow2

:

With Junos 20.2R1.10, the vQFX provides robust support for modern constructs. You can build 5-stage Clos networks completely in software to evaluate: Type 2 Routing: MAC/IP advertisement for host connectivity.

The RE and PFE must be interconnected in your virtual workspace using dedicated backplane links to function as a unified virtual switch. Key Technical Specifications gns3-registry/appliances/juniper-vqfx-re.gns3a at master

The vqfx-20.2R1.10-re-qemu.qcow2 file serves as the control plane, running Junos OS. It handles management, routing protocols (BGP, OSPF, EVPN/VXLAN), and configuration.

Understanding and Deploying in Network Labs

Designates this specific file as the Routing Engine image, not the Forwarding Engine (PFE). : With Junos 20

The virtual image is a critical software component used by network engineers to emulate the control plane of a physical Juniper QFX Series switch . This specific QCOW2 file represents the Virtual Routing Engine (vRE) for version 20.2R1.10. It runs the JunOS operating system, handling routing protocols, policy configurations, and management operations within virtual network labs.

: EVE-NG requires strict naming conventions. Create a directory starting with vqfxre- . mkdir -p /opt/unetlab/addons/qemu/vqfxre-20.2R1.10/ Use code with caution.

Tell me which emulator you are using (GNS3 vs. EVE-NG), and I can give you a troubleshooting guide.

You should see revenue ports ( xe-0/0/0 through xe-0/0/X ) switch from an unassigned state to an up/up state. Troubleshooting Common Issues 1. Interfaces Are Missing or Stuck in 'Down' State This link or copies made by others cannot be deleted

: Running virtual appliances requires adequate hardware resources (CPU, RAM, and disk space) on the host system to ensure performance.

Integrate the lightweight virtual RE into automated Jenkins or GitLab pipelines to pre-parse syntactic configuration adjustments before deployment to production environments. Share public link

: Check your topology connections. Ensure em1 is directly linked to em1 on the PFE, and verify both VMs are powered on. 2. Infinite Boot Loop or CPU Spike

A widely documented quirk of this specific evaluation image is that while the filename indicates version , the internal software often reports as 19.4R1.10 upon booting and running show version . Hostname: Defaults to vqfx-re .
