Maybe this is a stupid question, but has anyone ever passed the CCIE lab only practicing on with Dynamips? And is there some sort of cheat sheet on how to use Dynamips to prepare for the CCIE exam? Looking at Dynamips, it seems like it can't simulate switches. How can one prepare for the CCIE lab exam with Dynamips if it can't simulate switches? Can Dynamips be used for v4?
