Hi Ben Pfaff,

Thanks for reply.

I tried to enable multicast snooping but i was not able to do that,
currently i am using ovs-2.3.0 but i am not sure that it supports multicast
snooping or not.

Can you please confirm me either it (OVS-2.3.0) supports multicast snooping
or not, and if not then which version should i use.
