UPDATE: I highly recommend anyone interested in Dynamips to check-out GNS3 (Graphical Network Simulator). It’s designed around Dynamips, Dynagen, and Pemu. Cisco IOS/PIX binary images not included!

Dynamips is a Cisco router emulator. It support various Cisco 2600, 3600, 3700, and 7200 series router models.

Dyangen is a front-end for Dynamips router emulator. It utilizes Dynamips’ Hypervisor mode to make lab simulation management very easy.

Installing / Running Dynamips and Dynagen on Windows (XP, 2003, Vista):

• Install WinPcap 4 (Windows Packet Capture Library) from WinPcap.org (link to auto-installer).
• Install the latest version of the Dynamips/Dynagen “package” installer from SourceForge.
  NOTE: April 29th, 2007 build is labeled: dynagen-0.9.2_dynamips-0.2.7-RC3_Win_XP_setup.exe

NOTE: Users with Vista UAC enabled may encounter issue(s) when trying to run Dynamips/Dynagen. Solutions:

1. Disable UAC!
2. Run the Dynamips server and Dynagen as Administrator; however, you must first modify the “dynamips-start.cmd“, “dg-local.cmd“, and “Network device list.cmd” script files, located in the DynMIPS installation folder:
   (e.g.:
   Before: start /belownormal /B /wait “Dynamips” “dynamips.exe” -H 7200
   After : start /belownormal /B /wait /D “\Program files\Dynamips\” “Dynamips” “dynamips.exe” -H 7200
   )
   UPDATE: Check my next blog entry to download the updated startup scripts (.cmd) files.
