Learn Cisco Routing and Switching with IOU/IOL Images on Eve-ng


How to Download and Use IOU Images for EVE-NG




If you are preparing for Cisco certifications or want to practice Cisco networking technologies, you might have heard of EVE-NG. EVE-NG is a network emulator that supports virtualized commercial devices and open-source routers. One of the types of images that EVE-NG can run is IOU, which stands for IOS on Unix. In this article, we will explain what EVE-NG and IOU are, how to download and use IOU images for EVE-NG, and how to test and troubleshoot them.


What is EVE-NG?




EVE-NG stands for Emulated Virtual Environment - Next Generation. It is a clientless network emulator that provides a user interface via a browser. It allows you to create virtual networks with various devices from different vendors, such as Cisco, Juniper, Arista, Huawei, and more. You can also use Docker containers, Linux machines, Windows servers, and other tools within your network topology. EVE-NG can be used for learning, testing, proof-of-concept, or demonstration purposes.

Features and benefits of EVE-NG




Some of the key features and benefits of EVE-NG are:



  • It supports multiple virtualization technologies, such as QEMU, KVM, Dynamips, Docker, and IOL/IOU.



  • It has a simple and intuitive topology designer that lets you drag and drop devices and connect them with a click.



  • It allows you to import and export network configurations, labs, and pictures.



  • It has a custom kernel that supports L2 protocols, such as STP, VTP, DTP, CDP, LLDP, etc.



  • It has a memory optimization feature that reduces RAM usage by sharing identical memory pages among devices.



  • It has a CPU watchdog feature that monitors the CPU load and stops devices that consume too much CPU resources.



  • It has a full HTML5 user interface that does not require any additional tools or plugins.



  • It supports multiuser collaboration and interaction with real networks.



  • It has a rich integrated text editor that allows you to edit text and objects in your lab.



  • It has a lab chat feature that enables communication between lab users.



  • It has a lab timer feature that helps you manage your self-training time.



Alternatives to EVE-NG




EVE-NG is not the only network emulator available in the market. There are some alternatives that you can also consider, such as:



  • Cisco Packet Tracer: a free network simulation and visualization tool for Cisco devices. It is mainly designed for CCNA level labs and scenarios.



  • GNS3: a free and open-source network simulator that supports multiple vendors and platforms. It requires external hypervisors, such as VMware or VirtualBox, to run devices.



  • Free SNMP Agent Simulator: a freemium tool that simulates SNMP devices and traps. It can be used to test SNMP-based network management applications.



  • NetSim: a paid network simulator and emulator that supports Cisco, Juniper, and other devices. It has pre-built labs for various certification exams.



Dynamips: a free and open-source Cisco router emulator. It can run IOS images without any modifications What are IOU Images?




IOU stands for IOS on Unix. It is a type of image that can run Cisco IOS software on a Linux platform. IOU images are mainly used for internal testing and development purposes by Cisco engineers. They are not officially supported by Cisco for customer use. However, some authorized customers may have access to IOU images for their own testing and learning needs.


Types and versions of IOU images




There are two types of IOU images: L2 and L3. L2 images can emulate Cisco switches, while L3 images can emulate Cisco routers. Both types of images can support various features and protocols, such as VLANs, STP, OSPF, BGP, MPLS, etc. However, they may not have all the functionalities and commands of the real devices.

Advantages and limitations of IOU images




Some of the advantages of using IOU images are:



  • They are lightweight and consume less resources than other types of images, such as QEMU or Dynamips.



  • They can run multiple instances on a single server without affecting the performance.
