Just curious why Jeremy Cioara recommends not reading Jeff Doyle's books?

Everyone who goes for the exam seems like they have these books on their list and Brian McGahan says you need to know everything from these books in order to pass. I think Jeremy is a great teacher, helped get me my CCNA, but is it probably because he took his CCIE a while ago and CBT Nuggets doesn't cover CCIE too heavily so he's not up to par on what's on the exam these days?

The book is goes deep. You don't need it for the LAB test. You will understand once you take the test.

Well, he states his reason in the video. He thinks the books are full of unnecessary details. I disagree with him.

First of all, Doyle's explanations of protocol mechanics are second to none. The idea that you can master protocol configuration without understanding the theory is false in my opinion. That's not to say you need to understand every detail in his books, but let's just say if you haven't acquired the info at some point you are going to have a hard time.

Second, Doyle's book is full of examples. When I passed my CCIE (granted, many years ago), I tried every scenario he presented in the lab. You may be able to get some of this experience from doing the labs that are published by vendors, but Doyle's focused examples with clear explanations are very informative.

I passed in one attempt and I am convinced that they key was understanding protocols in depth rather than just knowing lab scenarios. (See my blog under "10 years a CCIE" for more info on solid CCIE preparation.)

At the end of the day, when I actually got a job at Cisco on the routing protocols team in High Touch TAC, I was glad I hadn't just studied for the test, but had studied the protocols in depth. I still had a lot to learn, but a very solid foundation.

Honestly CBT is a bit out of touch with IE content. They are good for introducing content from a basic-to-intermediate level only. INE is where you want to be if going after IE material and I heavily suggest people read Jeff's book and also these:

Reading the doyle books is good stuff.

Will it help you with the lab or the horribly worded written. Probably not.

Understanding the protocols at a deeper level will certainly help you with the CCIE and how to troubleshoot those protocols.
