[phpbay]cisco lab,1[/phpbay]

While waiting for my lecture my laptop got hotspot signal. I hate waiting, so I try to install GNS-3 in my windows XP laptop.

What is GNS-3?

Taken from GNS-3 site :

"GNS-3 is a graphical network simulator that allows you to design complex network topologies. You may run simulations, or configure each device, from a simple workstation to a powerful Cisco router.

To allows complete simulations, GNS-3 is based on two existing projects:

  • NS-3 , a discrete-event network simulator for Internet systems, targeted primarily for research and educational use.
  • Dynamips, an IOS emulator which allows users to run IOS binary images from Cisco Systems.

GNS-3 is an open source product that may be used on multiple platforms, including Windows, Linux, and MacOS X.

 Features overview

In the current version (alpha release) which is still under heavy development, GNS-3 works only with Dynamips. The ns-3 simulation mode has not been implemented yet.

Currently supported features:

  • Design of high quality network topologies.
  • Emulation of Cisco routers.
  • Load-balancing on multiple hosts/hypervisors when in emulation mode.
  • Topology import and export.
  • Image exports (PNG, JPEG, BMP, XPM)."
