CCNA Network Simulator 1

CCNA Network Simulator is a software tool that simulates a router/switch network. The tool should typically be able to:

• Simulate a router
• Simulate a switch
• Simulate a router/switch network
• Design a router/switch network
• Save semi-finished configurations, and reload for later resumption
• Save the work to a text file for later use.

A router simulator is essential for having hands-on practice. Ofcourse, if you can buy routers and switches and make physical network that would be fine, but normally does not justify the costs involved.
