    Routes! Routes tell network packets how to traffic across the network to get to their required destination by picking the best path. There are three different types of routes such as default routes, static routes and dynamic routes. Each one has its own pros and cons.  Routes are stored in…

    Home Lab Setup for CCNA/CCNP/Networking There is always “the great debate” when you’re studying for your certification exams if you should build your lab with hardware or software. In my opinion, what I have done is gone with both. I think you should have 2-3 routers, 2 switches and sometime…
