file, this runs the Junos OS control plane. It handles management, protocol processing, and configuration. Packet Forwarding Engine (PFE): Often a separate file like pfe-qemu.qcow , this simulates the data plane and ASIC behavior Practical Applications These images are indispensable for several reasons: Juniper vQFX - - EVE-NG
(on vQFX-1):
Minimum 3 (The VFP is CPU-hungry because it simulates hardware ASICs). RAM: 2GB to 4GB is the sweet spot. Disk Format: QCOW2 (Native for QEMU/KVM). Step-by-Step Deployment (EVE-NG / GNS3) 1. Preparing the Image
: Unlike the vSRX, the vQFX is optimized for Layer 2 Ethernet switching, making it ideal for JNCIA, JNCIS, and JNCIP study.
Initial setups often include extensive default configurations that can conflict with lab topologies. You can enter the configuration mode and use delete from the top hierarchy, but you must ensure the em1 interface configuration is preserved to keep the RE and PFE linked.
Here is a long write-up detailing what this specific image is, its role in virtual networking, and how to deploy it.
