Hi Pradip, Everything I figured out for installing Dynamips/Dynagen on Ubuntu and getting my lab working came from the following:
http://www.xaero.org/index.php/articles/installing-dynamips-and-dynagen-on-ubuntu-710/ http://21500.net/?p=666 http://blog.ipexpert.com/2011/02/28/gns3-and-physical-switches-breakout-switch/ The only other magic is the idlemax setting. The blog link from IPExpert has an example .net file for the IPX topology. I tweaked mine a little, but it is very similar. Hope that helps, Bob On Friday, February 24, 2012, Pradip wrote: > Hi bob, > > Can you guides us how to installed??
