Please, watch the video introduction to get familiar with some changes in the blog.
My Dynamips (Dynagen) LAN connections look like shown below:
Pic. 1 - LAN Connections.
WAN links in my labs look as shown in the pic. 2:
Pic. 2 - WAN Connections.
If you use dynamips+dynagen on Linux (like myself) you might find the following topology file useful (keep in mind I start TWO instances of the dynamips hypervisor to off load the CPU).
