I attended two CCIE courses, the first one was Narbik’s CIERS-I + bootcamp and the second one was IP Expert’s CCIE One Week Lab Experience. My goal was to see materials from different vendors for workbooks and bootcamps to get as much variety as I could.
Understanding the theory of each protocol is one thing, but being able to configure it is another thing. After reading a number of books, I purchased a collection of CCIE R&S practice workbooks. The first set that I purchased was Internetwork Expert’s workbooks (Vol1, Vol2 and Vol3) to get my hands on experience with each CCIE topic. Once I was finished the majority of INE workbooks, I bought IP Expert Volume 2 and Volume 3.
