In this article I want to show you how to extend your posibilities to test a network in GNS3. Sure, it’s simple sometime to use a Loobpack interface on one of your edge routers to simulate an external network, but sometime is useful to have something connected to the router port. Take as an example...

GNS3 is an extremely useful tool if you are using Dynamips to emulate Cisco devices. It is a graphical environment in which even a newbie can do complex configuration by clicking and dragging routers, switches, connections into a topology that can be saved. The problem that occurred to me in the past...

Most of you already know that in Dynamips after a reload of a switch all the vlans and vtp configurations are gone. There is a way how to save the vlan and vtp configuration even in case of a reload of the switch and I will show you below how to do it. For switch emulator I used a Cisco 3640 IOS image...
