Remember, the vQFX is a dual-image system. You cannot move traffic with just the RE file. You must pair it with a vQFX-PFE (Packet Forwarding Engine) image. The RE handles the CLI and routing protocols, while the PFE handles the actual "cabling" and data transit. Best Practices for Setup

If the switch comes up, you are ready to monitor it.

The Juniper vQFX is a virtual switch that emulates the behavior of a physical QFX Series switch. It is widely used for:

If you prioritize I/O performance over snapshot features, convert the image to raw:

In the EVE-NG UI, add the RE and PFE nodes, and connect their em1 interfaces together. Optimizing vQFX Performance

To successfully boot this specific image, it must be mapped into your virtualization environment alongside its corresponding PFE disk companion. Guide: Importing Juniper vMX and vQFX into CML2.4

This runs the Junos control plane (routing protocols, CLI, management).
