New Topology Diagram

After a looong hiatus regarding my blog updates I come back with new set of mini labs and new topology.

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).

My next series of mini-labs (starting with Lab 168) will use the above layout until further notice.
