Re: Idle-max value in Dynamips

My solution to this was to use 4 3550s in my lab and only emulate the
routers. While this was more expensive than a full GNS3/dynamips lab, it
was certainly cheaper than a full lab. The only shortfalls I have currently
are 3550 vs 3560 feature-wise. Best of both worlds really. Would I have
preferred a full rack of gear? Of course, but reality intervened in my
case.
