In GNS3, navigate to Preferences > QEMU VMs and click New .
Connect (or the first operational interface depending on template settings) of the RE node to Port eth1 of the PFE node. This link acts as the internal control plane bus.
: 2 GB allocated strictly to the RE VM (The paired PFE will require an additional 1 GB to 2 GB). Vqfx-20.2r1.10-re-qemu.qcow2
(Note: The folder prefix must be exactly vqfxre- so EVE-NG maps the correct template). Step 2: Upload and Rename the Image
By understanding its split RE/PFE architecture, its specific network requirements (particularly the virtio-net-pci NICs and the 12-NIC limit), and its known behaviors, you can successfully deploy it in your virtualization environment of choice. While it has its quirks and should not be used for production, it remains a highly valuable tool for learning and testing Juniper's data center technologies.
: For standard lab testing of BGP, OSPF, LLDP, and basic EVPN, these license warnings can be ignored as the features remain functional in software-emulated environments. Conclusion : vqfx-20
Like many virtual appliance files, the name Vqfx-20.2r1.10-re-qemu.qcow2 is a human-readable metadata string. It contains precise information about the device type, software version, and format, which is essential for its correct usage in network automation scripts (e.g., SaltStack, Ansible, or other management tools), as seen in various automation projects:
To avoid corruption of the live file system, always use the command request system power-off both-routing-engines (or halt ) before shutting down the VM.
Unlike standard network emulators that wrap everything into one image, the vQFX splits the system into two distinct virtual machines. This architecture mirrors physical hardware mechanics: This link acts as the internal control plane bus
