Excellent God Send

I love the way Rene breaks down a technology by showing the lab with the commands also going deep on various topics.

Useful & Easy

What I like about NetworkLessons.com, is it offers the ability to go back to the fundamentals of networking. Which always come up, even if I am working on more complex technologies. The simplified nature of the labs of NetworkLessons.com makes rebuilding them a breeze. I also like that new technologies and lessons are constantly being added.

Excellent & Helpful

I feel Rene is very helpful especially when I need help in my job in Cisco. My previous experience is with Linux systems and any open-source projects, creating various services ranging from DNS, Web services to OpenVPN, and OpenRadius. Plus maintaining security of servers. I am currently working at a Stocks Exchange Software company, which requires me to have knowledge both in Cisco, and Unix. I have some basic knowledge on Cisco, however my job requires to have more in-depth knowledge especially in multicast. One thing I love in enrolling on Network Lessons is because of Rene, I feel he is a very helpful and talented Cisco Network Engineer. Hopefully I will learn a lot on Cisco and he may help me, since I started to love Cisco.
