In order to use dynamips you need to have a Cisco IOS Image a Cisco Router. The Image is not part of this software! Dynamips is not DSFG compliant and will be included in non-free until "microcode" binary in source tree is compilable from source. Therefore a Cross-Compiler-Environment is needed, which is not the case right now. Erik Wenzel , Sat Jan 13 15:09:56 UTC 2007
