Hello everybody, The problem , if I use only pyswitch I don't get any flows. But I will try tomorow morning and I will send the error I get with pyswitch.
Me too I have a loop in my network and like you see I have some problems. When you tell "add static routing in nox" how are you doing that ? Which file you are modifying ? Because I have two host and they are not able to ping. So I don't know how to defined the route into NOX. Thank You Julien Ratinaud 2012/5/20 Qingyun Zuo <[email protected]> > Hi, recently I used "routing" component in my mininet.
