CCIE Routing & Switching
I finally got my CCIE (#62941)! I used INE as my core material for studying for the CCIE RS exam. INE's CCIE RS workbooks (and probably the other tracks) are extremely good, and I would recommend them to anyone seriously pursuing their CCIE. The CCIE RS 5.1 material by Brian McGahan was amazing, and if I had trouble with a particular technology there was usually a "deep dive" series that really helped drive the concepts home for me.
