This type of attack is mitigated by the MLD state machine. When a router receives a Report that signals no more interest in a particular group it first sends out a group-specific query to ensure that interest does not exist. When that query is sent, the target node will respond that it is still interested. > > 2. protection against spoofing of multicast Listener > query messages in which a rogue node with a lower IPv6 > address than the current querier will cause querier > duties to be assigned to the rogue node. This would be useful in my opinion. Regards, Brian [behcet] I think these (or this) issues need better be handled in multicast related WG in int area, magma is one. We recently started multimob mailing list (cc'ed), if the above issue is likely to arise in mobile environments, multimob could also be considered.
