He is my go-to person for anything EVPN VXLAN / Data center related queries... interacting with him is usually a learning experience in itself for me.
Manasa Suresh, HPE
The only name I can think of when it comes to Core Switching is Aninda... His troubleshooting and client handling skills are remarkable.

It's a well written book! Great for learning data centre networking with juniper gear! It's one of my primary tools of learning DC.

I was lucky enough to get this book from Juniper for free. I love this book. The book covers these topics in so much detail. It talks about theory and shows you the configurations and commands in every chapter. This book is a must have if you are studying for Junipers DC certification track. Take it from a CCIE/JNCIE networker, get this book.

I received my book today and I'm impressed with the content. Really nice book, covering everything you need to know for JNCIE-DC and JNCIP-DC. I could say that this book cover all Data Center track because you'll find all topics of the fundamentals of D.C (JNCIA-DC) and Juniper Apstra as well (JNCIS-DC). Additionally, there are many images and CLI configs as examples, including Wireshark screens to help you to understand all traffic flows.
