Start both nodes. The vCP node can take up to 5–10 minutes to boot fully and initialize the Junos CLI interface. 6. Resources Optimization and Troubleshooting
If you haven't already, download EVENG from the official website ( www.eveng.com ). Follow the installation instructions to install EVENG on your computer.
Before searching for a download, you must understand why free EVE-NG struggles with vMX.
This VM runs the Junos OS routing engine. It handles all control plane traffic, routing protocols (like OSPF, BGP, and IS-IS), and system management interfaces. In EVE-NG, this is usually named using the prefix vmxvcp .
To download Juniper VMX for EVENG, follow these steps: juniper vmx download for eveng free
Upload junos-vmx-x86-64-21.4R1.12.qcow2 to /opt/unetlab/addons/qemu/vmx-vcp-21.4R1/ and rename it to virtioa.qcow2 .
Network engineers use EVE-NG to build complex labs and test configurations. The Juniper vMX (Virtual MX) is a full-featured, carrier-grade virtual router. It runs the Junos operating system and mirrors physical MX series routers. Testing Junos features requires importing a vMX image into your EVE-NG topology.
Runs Junos OS. It handles routing protocols (OSPF, BGP, MPLS), management, and system configuration. This is usually named vmx-vcp or vrr .
When adding the nodes inside the EVE-NG web interface, use these resource guidelines to prevent your topology from crashing: Requires at least 1 vCPU and 2048 MB (2 GB) RAM . Start both nodes
Use an SFTP client like (Windows) or FileZilla (cross‑platform) to transfer the vmx-bundle-*.tgz file to your EVE‑NG server. Place it in the /root/ directory.
Choose the KVM bundle (typically named something like vmx-bundle-<version>.tgz ). This archive contains the necessary QCOW2 images for the Routing Engine (VCP) and Packet Forwarding Engine (VFP). Download it to your local machine.
: If your local machine isn't powerful enough for the heavy RAM requirements of vMX, Juniper offers free cloud-based vLabs that are ready to use instantly [31]. Support Community : If you hit a snag, the Juniper Elevate Community
The VCP and VFP must be linked directly to communicate with each other. This VM runs the Junos OS routing engine
Some users have reported seeing an "ERROR: Unlicensed" message when trying to run vMX nodes. This typically occurs when using EVE-NG Pro instead of the Community Edition, or when permission fixes haven't been properly applied.
Note: Avoid downloading the VMware ESXi (OVA) versions, as the KVM deployment bundle contains the native .qcow2 files that match EVE-NG’s underlying architecture. Step 2: Preparing the vMX Folders in EVE-NG
Before you can download Juniper VMX, you need to create a Juniper account. Go to the Juniper Networks website ( www.juniper.net ) and click on "Register" in the top right corner. Fill out the registration form with your details.
Once the download completes, you will have a .tgz or .ova file. EVE-NG specifically requires .qcow2 image files for its nodes.
