dynamips files for the demo lab

The free demo lab, which can be downloaded here, is a huge success.
Many ask me to send them the dynamips version of the initial configurations and .net file.
Since dynamips do not support switches, please skip the L2 tickets, which is ticket #1 on the demo lab.
Please follow the instructions found here about how to use the lab file.
