Networking (Hardware)

Networking hardware commonly includes switches, routers, and/or firewalls.



The Graphical Network Simulator 3 (GNS3) is a free and open source software for setting up virtual lab environments consisting of switches and routers. Virtual images are provided by most of the major network manufacturers that can be used with GNS3. [1]

The GNS3 Marketplace provides many templates that mirror configurations and hardware that production devices use.
