Introduction

I am Babak Dorrani, I am a Cisco network engineer working in an International company in the Netherlands.
While I was living in my home country, Iran, I was also involved in Cisco networking and mostly in teaching some Cisco courses. Fortunately my old students have not forgotten me yet and they still send me their problems and questions and I am more than happy to help them out (if I can!).

After about two years being away, I decided to put these questions and answers, which are now quite a lot, here in this blog mainly to share them with others and discuss about them.

In most of the cases the questions are in Farsi language so I do not mention the exact question here to make it a bit more useful for my international friends. From now on I will try to translate the questions but for the previous ones No Way!!

And one last thing, please correct me and let me know in case you find any mistakes in my writings.
Good Luck!
Babak
