GNS3 normally comes across the paths of those who are studying for a certification exam from Cisco. If you haven’t encountered it yet then you are missing out and logging behind something that’s awesome! GNS3 is a simulator of a network that graphically runs Cisco images allowing you the comfort of just dragging and dropping some routers and manually connects them to create different situations and scenarios which are good to be studied. This is commonly used by most network engineers in their daily jobs, network setup testing, changing of routers and trying new features. Other experts also use GNS weekly just for testing some things that are relevant to their jobs. Visit to read about gns3 images download free.
The problem surfaces when you’re using gns3 images on a windows PC. It sometimes literally sucks since running more than 5 and above routers on the CPU causes it to be pegged which stops you from doing anything else on your machine. There’s a vast of forum posts available over the internet discussing possible solutions to this common problem but tries normally fail which becomes a major reason why most just gives up on GNS3 after several tries. One solution however is by using Ubuntu, an operating system that is more memory efficient which allows you to run up to 20 routers without sacrificing CPU performance. Now, the question is what if you are not that confident with Linux OS?
That’s where GNS3 workbench comes into play. It was developed by an Australian in the name of Chris Welsh. GNS3 workbench is a type of VMware image that has Ubuntu OS component and a gns3 switch image already combined in one setup with all the needed optimizations. The thing that you only need to have is an IOS from Cisco.
Everything starts with a simple download of some vmdk files from his website, put everything in one folder on your laptop or PC then start a VMware reader/player or another common application called VMware workstation to run the virtual machine. These things really works but before using it, secure the Cisco IOS first and make sure that the platform is developed around the requirements of a c3725-adventerprisek9- mz.124-15.t10bin. The image from Cisco is not provided on the file that is downloadable from the website due to licensing reasons. Tutorials are also available on the website as well as useful exercises that cover some relevant Press materials from Cisco. Check this out for gns3 cisco images
