If your system happens to have WinPCAP 4.1.3 already installed I recommend unchecking it to save some time.Ĥ. When you get the components you can choose what else you want installed, you will likely want to keep everything checked unless you already have Wireshark etc installed. Now we will go through the fairly boring install, basically keep clicking next.ģ. Download GNS3 and also the GNS3 VM image.Ģ.I’ll be doing the Windows installation, the Mac version isn’t terribly different aside from the actual setup screens, Linux is a bit more involved but you are probably expecting that to be the case if your a Linux user 🙂 Let’s look into installing GNS3, it supports Windows, Linux, and Mac so pick what makes sense for you. Likewise your on your own when it comes to getting your hands on IOS images. However Cisco doesn’t condone by the public so while I will likely use IOU from time to time in this workbook I won’t provide any pointers on how to set it up or get its images.

Note: A word about IOU, IOU is a leaked internal tool that Cisco uses to simulate network topologies, the CCIE lab is also run on a variant of IOU.

Native switching is very poor though IOU provides a switching experience that is closer to VIRL.

Also there is the odd bug and such with the solution.

You can occasionally experience weird behavior due in IOS if you are doing advanced tasks.

You need to get your hands on Cisco IOS or IOU images.

You can add and remove links on the fly.

Self contained, you can run GNS3 directly on your computer.

It also allows you to throw other vendors into the mix through VirtualBox or VMware Workstation integration. Using GNS3 you can effectively study from the CCNA level to the CCIE level across several tracks.

Unlike something like Packet Tracer which emulates Cisco devices and provides common commands that a CCNA candidate might need, GNS3 is a network simulator that runs actual Cisco IOS so you have access to the full command line and features.It also allows for nodes to have external connectivity so you can connect your routers to connect to the internet or your local servers.
