The first requirement of the CCIE Lab exam is to pass the written exam. The one and only resource you will need for this is the official CCIE routing and switching certification guide from Cisco. Written by Wendell Odom, Rus Healy and Denise Donohue. Now in it’s 4th Edition it covers the entire R&S Blueprint which also maps nicely to the blueprint for the lab exam. I have already passed the written exam but let it expire, so before I book my lab I need to pass the written again. I was glancing through the topics of the fourth edition to see what extra has been added since the third edition. On first glance it appears to cover a bit more on MPLS and Router and Switch device security.
My advice would be if you already have the third edition to just look at the official Cisco R&S blueprint and ensure you have read up on all the topics. If you do not own the third edition then the purchase of the fourth edition should be the first thing you buy for your CCIE exam preparation.It is a great book to start with to expand on the knowledge gained in the CCNP.
Good luck with your studies.
