In the CCNA course, there is some type of network diagram for reference. What is the software used to make those diagrams? I'm curious, because I am looking for one that is that easy to draw a network map.
Network Diagram software
The diagrams that I created in the CCNA show was made in SimpleDiagrams4. You can find it at www.simplediagrams.com.
We've been using it since the beginning of ITProTV 7+ years ago and still use it today. I like it but having said that. I'm not going to say it's easy to use. But they have a 7 day trial you can download and try.
