Thanks for the excellent video, about the understanding of Protocol and Algorithm to be a proper network engineer, I do agree ,but whenever I went for a round of interview for network engineer job, they ask about specific commands, configuration and etc. How to face these ? Also there are lot of different implementation of protocol like BGP ( Quagga,Exa,SnapRoute, GoBGP) etc how to move forward with all these .
The edge between the old and the new is always the hardest place to live… Companies are going to continue to ask you questions about CLI/etc. for a while yet, I think, and some companies will probably be asking these kinds of questions until they go out of business. 🙂 The best advice I can give is to learn the fundamentals, and then balance your time between learning the old and the new as much as possible.
