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

Create a bridge for the management network and a dedicated bridge for the switch ports.

# Management bridge (virbr0 is default, but we want a routed bridge)
sudo brctl addbr mgmt-br
sudo ip addr add 192.168.122.1/24 dev mgmt-br
sudo ip link set mgmt-br up

Booting with QEMU/KVM (example procedure)


Create/adjust qcow2 backing or copy if needed:


Basic QEMU command (adjust CPUs, RAM, NICs):


libvirt: define a domain XML mapping the qcow2 as the disk, add virtio NICs, set memory/vCPU, and boot.

This is the most common platform for this specific image format. Below is the standard procedure to install it.
EVE-NG looks for specific filenames. You usually rename the RE image to hda.qcow2 and the PFE image to hdb.qcow2 (depending on the specific template, sometimes the naming convention varies, but standard vQFX setups often map RE to the first drive).
However, for the vQFX specifically, the standard naming convention in EVE is usually: Vqfx-20.2r1.10-re-qemu.qcow2

(Note: Check your specific EVE-NG template for vQFX, but the directory name vqfx-20.2r1.10 is crucial for the platform to recognize the version).
Never run the base image directly. Use a backing file to create instances.
# Create a directory for your lab
mkdir ~/vqfx-lab
cd ~/vqfx-lab
| Area | Limitation |
|------|-------------|
| Forwarding performance | PFE is software-emulated – <1 Gbps, high latency. |
| EVPN | Partial support – use 21.x or later for production-like EVPN. |
| VXLAN routing | May require rebooting PFE after changes. |
| SNMP bulk walks | Can cause RE CPU spikes. |
| Graceful Routing Engine Switchover (GRES) | Not supported in single-RE images. |
| Upgrade path | Must upgrade both RE and PFE images together; 20.2 → 21.2 is possible but nontrivial. |
Juniper typically provides these images via the official Juniper Download site (requires a support contract) or a Juniper vLabs trial. If you have access, search for "vQFX 20.2R1.10."
