Also, Windows in not really an optimum platform for a full IEWB
topology. It can be done with the kind of HW you're talking about, but
it will be hogging your CPU for sure...

In regards to your first issue you may try to have Dynagen determine
the
best idle-pc value after the routers have booted up. You can do this
by
not setting the idle-pc value in your .net file but after the routers
have
booted up get on the Dynagen console and type "idlepc show <device>".
Dynagen will now show you the "best" idlepc values. You can then
select
one to try and if it works you can save it by typing "idlepc save
<device>
default".
We actually offer a version of our IEWB Vol 2 workbook specifically
written for Dynamips. That being said you should be able to modify
your
existing labs to work in Dynamips with a little effort.
