This course is all about BGP and all features that you can find to use your router as a Border Gateway Protocol router. 

I have explained all commands in detail so that you can easily get a grab on that feature. If you cannot find a feature, this means either it is obsolete and a better feature replaces that or I have forgotten to include it.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.
