Reddit reviews CCIE Routing and Switching v5.1 Foundations: Bridging the Gap Between CCNP and CCIE (Practical Studies)

Start with CCIE blueprint. It has everything you will need. Start and assess your self first. When you identify areas you're weak, you can then work on referring to even more materiel to better your understanding.

Since you've reached CCNP, it would be best to pick up this book to bridge the gap between CCNP and CCIE (https://amzn.com/1587144727)

I would recommend to at least do the 360 (especially the CA-20's and the INE labs. And whatever else you can afford honestly. The advantage of multiple labs is you get used to different ways of items/questions being asked. And possibly see different solutions. INE covers a pretty large variety. The 360 I felt was a lot closer to the real thing than anything else I've done. Although its not 100% identical or anything. The graded labs are interesting for the 360 stuff but not 100% accurate. I do like how you can compare your config to the key though and run output commands to see the differences. I would recommend checking out some of Narbik's stuff. He has a book called "CCIE Routing and Switching v5.1 Foundational" that has some good stuff in it. Along with his CCIE R&S Workbooks. I highly recommend those. I thought they were much better then the INE labs and they explain things a lot better. His workbooks are here https://micronicstraining.com/ and the book I'm talking about is this one. https://www.amazon.com/CCIE-Routing-Switching-v5-1-Foundations/dp/1587144727 Additionally I have heard good things about Jazari. I have not done those though. https://jaziri.training/ Congrats on the test and best of luck on the long road ahead!
