    All-Round Solid Site

    Whenever I navigate the Cisco website looking for info on network protocols, concepts, and config examples, I feel overwhelmed and would prefer to not have to read a novel. I love Cisco, but sometimes all you have is 10 minutes. NetworkLessons.com resolves that by packaging network concepts, protocols, and services, in a clear and concise format. Without skimping on the pertinent info. It is also good for when I want to spin up a quick lab in EVE-NG and follow config examples. An all-around solid site!

    Very Helpful for CCIE

    NetworkLessons.com was very helpful in bridging my knowledge gap in preparation for CCIE. Their lessons, together with the labs, were made to be concise and understandable. More importantly, they provide demonstrations from packet level using wireshark and debug commands, which helped immensely in building a strong foundation.
