Why Learn Network Automation in 2026?

Network automation is when you stop doing the same network work manually and let software do it for you in a controlled way. Instead of clicking around or typing the same commands on every device, you define the change once and apply it across the network, then verify the result automatically.

Let’s suppose you have 20 branch routers, and you need to add one new static route. Instead of logging into 20 devices and typing commands, you run one automation script that pushes the route everywhere and confirms each router has it.
