Router Software Was Used

It became so popular that it even surpassed other network virtualization training solutions.

It all started with Dynamips written by Christophe Fillot in 2005.

The software was used for emulation of some of the Cisco IOS on desktop computers.

And thats what changed everything for the many who love to spend hours running network labs.

Primarily the best host OS is meant to be Linux and thats also where you should get the best performance of it according to GNS3 creators.

Proudly, as an early contributor, my name has been added to the thanks to list coded in the new GNS3 Jungle release.

When it gets to CCNA, you can get your hands on Packet Tracer, which is sufficient for completing the CCNA course.

The best thing is always purchasing real equipment, but not everyone can afford the expense and the space required to store the kits at home.

GNS3 runs real IOS, without emulation or unexpected behaviour.

GSN3 is the perfect solution to have hundreds of topologies at hand, without the burden of real equipment installed somewhere.

When you fire your GNS3 software (which you can get for free here ) you need to load at least one IOS image: those are not included in the GNS3 package since they are licensed by Cisco Systems and cannot be freely distributed.

Here is a very simple topology to test basic functionality with GNS3 as router simulator.

They all use the same IOS that we added before in GNS3 preferences.

The Ethernet switch used is a part of Dynagen package, which provides a simple switch component with very basic functionalities.

It can be configured via GNS3, and theres no command line interface needed.

If you just need a very basic Linux box, this the thing you want.

I just dragged and dropped new vPC and connected to our switch.

As a simple CCNA lab in GNS3, lets make sure that we can reach all routers from one place.

It can simulate various degrees of complexity for networks, including simple switches, routers and virtual PC.

We focus on network fundamentals, productservice reviews, and career advancements.
