EVE-NG (Emulated Virtual Environment - Next Generation) is a popular network emulation platform that allows users to create and manage virtual networks. It provides a graphical user interface to create, configure, and connect virtual devices, including routers, switches, firewalls, and more. EVE-NG supports a wide range of virtual devices, including Juniper VMX.
For network engineers and Juniper JNCIP/JNCIE candidates, EVE-NG (Emulated Virtual Environment – Next Generation) is the holy grail of emulation. It allows you to run full Juniper JunOS instances without physical hardware. However, there is a persistent myth that running a (Virtual MX Series Router) on the free version of EVE-NG is impossible.
Inside the package, locate the standard virtual disk files: vmxhdd.qcow2 , vcp-junos.qcow2 , and vfp.qcow2 . Preparing EVE-NG Directories for vMX juniper vmx download for eveng free
Inside the extracted directory, look for the sub-folders containing the virtual disks. You are looking for two specific hard disk files:
In this paper, we have guided you through the process of downloading and setting up Juniper vMX on EVENG for free. By following these steps, you can create a powerful and flexible testing environment for your network configurations. With Juniper vMX and EVENG, you can test and validate your network configurations in a virtual environment, reducing the need for physical hardware and minimizing the risk of network downtime. EVE-NG (Emulated Virtual Environment - Next Generation) is
Unlike lightweight virtual routers (looking at you, vJunos-switch or Olive), the vMX runs a full Junos OS with real forwarding plane logic via a paired VFP (virtual forwarding plane) and RE (routing engine). It supports MPLS, EVPN, segment routing, advanced QoS, and scales to hundreds of Gbps in production. In EVE-NG, it lets you build service-provider-grade labs for CCIE/ JNCIE studies or SD-WAN testing.
Note: The free evaluation copy operates with rate-limited forwarding throughput (usually restricted to 1 Mbps or less), but all control plane features, routing protocols, and CLI configurations are 100% unlocked and free to use forever. 3. Preparing the vMX Images for EVE-NG Inside the package, locate the standard virtual disk
Look for the Forwarding Plane image, usually named something like vFPC-*.img or vFPC-*.qcow2 . Upload and Rename the VCP Image Connect to your EVE-NG server via SFTP. Navigate to /opt/unetlab/addons/qemu/vmxvcp-18.2R1.9/ . Upload the VCP .qcow2 file into this directory. Rename the uploaded file exactly to: Upload and Rename the VFP Image Navigate to /opt/unetlab/addons/qemu/vmxvfp-18.2R1.9/ . Upload the VFP image file into this directory. Rename the uploaded file exactly to: virtioa.qcow2 Step 4: Fixing File Permissions in EVE-NG
