CCNA R&S Labs: Learn by Scenarios

Learn CCNA R&S course by practical scenarios
English [Auto]
Basic implementation and configuration of Cisco IGP protocol features
Configure IPv6


  • If on GNS3, know how to create a topology in this environment
  • Very Basic knowledge about Cisco IOS


This course is all about Cisco CCNA R&S and everything you need to master your knowledge to become a decorated network engineer. 

I have explained all commands in detail so that you can easily get a grab on that feature. If you cannot find a feature or command, this means either it is obsolete and a better feature replaces that or I have forgotten to include it. In the latter case, I will be more than happy if you let me know what you want and I will add it to the curriculum.

I have used GNS3 for the simulation. However, you can execute all commands on a real gear without any change.

Who this course is for:

  • CCNA students
  • Anyone who wants to start Cisco routing and switching

I have trained more than 1200 direct and 45000 online students for CCNA, CCNP and CCIE Routing and Switching courses. 

I started as a Microsoft guy (like most of network experts!) and then ended up to become a network expert, first as a trainer and video tutorial presenter and then as a consultant for many small to medium to large enterprises. This consultant role gave me some huge and precious experience that I could add to my courses and make them richer than before.

I hope my courses on Udemy can help you to achieve your goals and become the one you wish to become.

Good luck with your studies!
