From the developer:
Dynagen is a front-end for use with the Dynamips Cisco router emulator. It uses an INI-like configuration file to provision Dynamips emulator networks. It takes care of specifying the right port adapters, generating and matching up those pesky NIO descriptors, specifying bridges, frame-relay, ATM switches, etc.
