In a simple terms it means that functions of such network elements as routers or switches are replaced by virtual machines (VMs) running a special software. One of the trends in today’s networking is called NFV, what stand for Network Function Virtualization. Today the networking and computing world is a bit another then 5-10 years ago, what simplifies the preparation for CCIE as well. But the time is passing by and things are changing.

In sake of justice I add that I was not preparing to CCIE in that time and even didn’t have such desire.

Days and nights I was working in the lab to understand how things are working. There was not only about preparation for certain exams, it was more about discovering the very exciting world of network technologies. In total 8 devices provided me possibility to prepare well for CCNP Routing and Switching and for CCIP, though I haven’t got the last one. It was very good time, as I had 4x Cisco 2600XM Series routers, 2x Cisco Catalyst 3550 switch, 1x Cisco Catalyst 2950 switch and 1x Cisco Catalyst 2958G 元. Personally I had such lab at home a couple of years ago as well. Therefore people, who were preparing for CCIE, used to gather together to share prices or refused this idea. Thanks to Ebay it was not too difficult, though it led to spending quite large amount of money. All other peoples, who desired to get CCIE, had to buy the used equipment on their own. Usually such possibilities had employees of big telecom companies or IT system integrators. The luckiest engineers had access to such lab at their workplace. History of home labs for CCIE preparationsįor decades there was the only way to prepare for CCIE Lab examination, which was the access to real equipment. Instant access to lab is crucial factor for success in career in overall and at CCIE Lab exam in particular.

In this post I’d like to provide you guidelines for creation of the home lab for CCIE Routing and Switching, Service Provider or Security.
