When Learning to configure our Network Devices we need to use a Virtualization Technology. This will be the canvas where we drag-&-drop our devices we need to configure. While there are many companies that provide this resource; Genesis Teaching has chosen to use GNS3 as the company and software of choice.
IOS IMAGES
An IOS Image is the file we need to run a Router or Switch in our GNS3 Software. Due to legalities we are not allowed to provide these images. Once acquired you may watch the corresponding video to learn how to install the image.
VMWARE
Dynamips is the default Cisco emulator that comes usable with GNS3 for the virtualization software. This allows for the use of older Cisco IOS images; as the newer IOS images are not supported with Dynamips. To make use of Newer IOS images as well as run Juniper code you will have to install and run VMware.
