The multicast snooping works as part of action NORMAL, so if you
are steering your traffic using other flow actions, then it wouldn't
work.

Yes, action is NORMAL. I am using Ubuntu-12.04 and man page of Ubuntu says
variables net.inet.igmp.v2enable and  net.inet.igmp.v1enable are enabled by
default in the link  "
http://manpages.ubuntu.com/manpages/precise/man4/igmp.4freebsd.html" . But
i am not able to see these variables in any of the files . I checked
/etc/sysctl.conf file also, but i didn't find anything in this file.

Can you please help me how to check IGMPv1 and IGMPv2 is enabled  or not in
Ubuntu-12.04 ?
