EVE-NG (Emulated Virtual Environment – Next Generation) is the gold standard for network simulation. However, a fresh installation is just an empty shell. To build labs for Cisco, Juniper, Windows, or Linux, you need the actual firmware, operating systems, and disk images.
Do not attempt to script downloads from Cisco or Juniper without authentication—you will be blocked and possibly reported.
Ethical and legal considerations form a critical part of the conversation regarding image acquisition. While various "mega-packs" and "all-in-one" download links circulate in online forums and gray-market sites, these sources often carry significant risks. Beyond the legal implications of software piracy, unauthorized image bundles may contain outdated, unstable, or even compromised binaries. The most reliable and professional method for obtaining images is through official vendor support contracts. Cisco Modeling Labs (CML), for instance, provides a legitimate path to download a wide suite of IOSv, IOS-XE, and NX-OS images that are fully compatible with EVE-NG. Download All Eve-ng Images
To set up a complete lab environment, you cannot download a single "all-in-one" file containing every image due to licensing and legal restrictions
…you can build a lab with hundreds of images representing almost any network device made in the last 20 years. How to Download All EVE-NG Images: The Ultimate
EVE-NG (Emulated Virtual Environment) is a powerful tool, but it is essentially an empty shell. It needs operating system images (Cisco IOSv, CSR1000v, Palo Alto VM, Fortinet, etc.) to function.
Finding reliable images often involves a mix of official, legal subscriptions and community-vetted repositories. Do not attempt to script downloads from Cisco
Server-grade EVE-NG labs with "all images" exceed 500GB. Here is how to manage:
To have a working “all images” setup:
