CCIE

I am aware of the fact that this is Ubuntu forum and my question doesn't match with the context. But i find it the most suitable place to put my curiosities before .

I want to clear CCIE ( Cisco ) and curently i have no idea how to proceed . I have gone through the book " Computer Networks" by Sir "Andrew S. Tanenbaum" and have basic understanding of protocols.

I began to study this book as I was interested in Operating Systems ( here Ubuntu )services that it provides to the Network.

I hope i'll get the right direction to proceed as usually got here.

Your help is heartly appreciated.
