The correct thing to do is silently drop the packet at source. Eg avahi will full join 224.0.0.251 which causes a send only IGMP packet to 224.0.0.22, and then a warning level kmessage like this: ib0: sendonly multicast join failed for ff12:401b:ffff:0000:0000:0000:0000:0016, status -22 If there is no IP router listening to IGMP.
