Hi Amjad,
Thank you for providing information. Unfortunately, I could not reproduce the problem. Looking at the log file you attached, I think the program worked good. > >> [snoop][DEBUG] > igmp(address='225.0.1.37',csum=2010,maxresp=0,msgtype=22) > >> [snoop][INFO] SW=00007e180dce0b47 PORT=1 IGMP received.

This is not under control of Ryu IGMP. Could you try on smaller topology for locating a problem? On Tue, 3 Jun 2014 14:56:24 -0400 Md.
