Network Engineering, explained simply
Notes from the CLI — a network engineer building, breaking, and automating networks.
Welcome. This is my working notebook as a network engineer — the place where I write down how routing and switching actually behave, how I automate the boring parts, and how I troubleshoot when things break at 2 a.m.
Everything here is meant to be practical: real CLI output, real configs, and topologies you can rebuild in your own lab. Start with the lessons in the sidebar, or browse thefull list.
