With the recently > added patch to disable snooping if there is no querier (b00589af + 248ba8ec05 > + 8d50af4fb), it should be a safe choice now (without these, patch 1/2 would > have introduced another potential for lost IPv6 multicast packets). > > Both conceptually and also with some testing and fuzzing, I couldn't spot > any more causes for potential packet loss. And since the multicast snooping > code has now been tried by various people, I think it should be a safe > choice to apply the multicast snooping not only for IPv6 multicast packets > with a scope greater than link-local, but also for packets of exactly this > scope. The IPv6 standard mandates MLD reports for link-local multicast, too, > so we can safely snoop them as well (in contrast to IPv4 link-local). Both patches applied, thanks!
