Double-check your topology connections. Ensure the interface designated for internal management on the VCP matches the internal link on the VFP. Wait up to 10 minutes; the VFP takes significantly longer to boot and sync with the control plane than standard routers. "Permission Denied" Errors
Rename the config/storage disk (if included) to: For the Forwarding Plane (VFP)

To add these images to EVE-NG, you must use an SFTP client (like WinSCP or FileZilla) or SSH directly into your EVE-NG server. Step 1: Create the Correct Directory Names juniper vmx download for eveng free
: Current Juniper customers can download a 60-day, unlimited-bandwidth trial from the vMX Trial Download Page vJunos-router : For a more lightweight lab experience, Juniper offers Free Virtual Junos OS Downloads for various platforms, including a specific vJunos-router. Evaluation Mode
: The trial technically lasts 60 days with unlimited bandwidth. However, once the trial expires, the vMX usually continues to function but is capped at 1 Mbps throughput —which is perfectly fine for most home lab learning. 2. Alternatives for Labs: vJunos
Re-run the /opt/unetlab/wrappers/unl_wrapper -a fixpermissions command in the CLI. Conclusion Double-check your topology connections
For an optimal lab experience, EVE-NG allows you to run a where the VCP and VFP are packaged together, or a split vMX image . Most modern EVE-NG setups utilize the packaged KVM evaluation images which are significantly easier to deploy. 2. How to Download Juniper vMX for Free Legally
Use the VFP interfaces (, ge-0/0/1 , etc.) for all data plane and transit traffic to other lab routers, switches, or firewalls. Step 6: Powering Up and Validating the vMX
: Without a specific trial key, the vMX usually operates with a throughput limit (e.g., 1 Mbps), which is sufficient for most functional lab testing like OSPF or BGP configuration. Juniper Elevate Community CLI commands for unzipping the bundle directly on your EVE-NG server? Juniper vMX 16.X, 17.X - - EVE-NG However, once the trial expires, the vMX usually
The vMX consists of two separate virtual machines that must be added to the EVE-NG QEMU directory VCP Folder /opt/unetlab/addons/qemu/vmxvcp- -VCP/ VFP Folder /opt/unetlab/addons/qemu/vmxvfp- -VFP/ 3. Upload and Rename Use a tool like WinSCP or FileZilla to upload the
Inside the extracted folder you will find two important files: one for the and one for the Virtual Forwarding Plane (VFP) . For EVE‑NG, you need to combine these into a single QEMU‑compatible image.
A: The vMX is resource‑intensive. Ensure your hypervisor supports hardware virtualization (VT‑x/AMD‑V) and that you have allocated enough vCPUs and RAM.
Juniper VMX requires a license to activate. For a free trial, you can obtain a license from Juniper's website. Go to the Juniper Software Downloads page and search for "VMX License." Download the free trial license and follow the instructions to install it.
: For perpetual lab use, Juniper now offers a specific vJunos-router image for labs, which is free and does not require a trial license. This is available on the Free Virtual Junos OS page .
