: Handles the actual transit traffic. Without the PFE, the RE can boot and you can configure it, but no traffic will pass between virtual interfaces. 3. Step-by-Step Integration
This specific file ( vqfx-20.2R1.10-re-qemu.qcow2 ) is available to authorized Juniper customers via the Juniper Networks Support Portal (Software Download Center).
Because you are running two VMs per virtual switch, the hardware requirements scale quickly. Hardware Requirements per vQFX Instance 1 vCPU, 2 GB RAM VFE VM: 2 vCPUs, 2 GB RAM Total: 3 vCPUs and 4 GB RAM per switch instance. Software Prerequisites vqfx202r110reqemuqcow2 work

To make vqfx202r110reqemuqcow2 work smoothly in a multi-VM lab:
This version is often favored by network engineers because it strikes a balance between modern Junos features and resource efficiency. It is robust enough to handle Juniper Apstra integration tests and complex leaf-spine architectures without the extreme overhead of later 21.x or 22.x releases.

The following flowchart illustrates the complete vQFX deployment process in EVE-NG:
By following the setup steps and being aware of common pitfalls like QEMU version mismatches and internal connectivity requirements, you can successfully deploy and utilize a vQFX node for your networking projects.
