Unlike VIRL/CML images (like vIOS) which require a full virtual machine instance for every node, IOL runs as a simple process on Linux. You can run dozens of these routers on a modest laptop without maxing out your RAM.

Alternate methods:

This image is part of the or IOL (IOS on Linux) family. Unlike standard IOS images that run on physical hardware (ASICs), IOL images are compiled specifically for x86 architectures. Platform : i86 (x86 32-bit/64-bit compatible). Operating System : Linux (runs as a user-space application).

Network engineers prefer IOL images like the 15.4.2t for several reasons: Alternate methods: This image is part of the

IOU images require a license key linked to your VM’s hostname and "hostid" to run.

Identifies this as a Layer 3 image (Router), which supports advanced routing protocols. Operating System : Linux (runs as a user-space application)
