I see in the IE routing and switching .net file that we are using two dynamips instances. How do you make another so that I can better apply a more suitable ios for that group of devices?
Umm, just start up a second instance of Dynamips. Same way you started up the first one, but with the port number specified in the .net file.
For me, it's simply:
dynamips -H 7201 &dynamips -H 7202 &
