_Advantages:_
- * Simplicity: - ** No multicast query snooping needed, only multicast report snooping - ** No state for querier +* Simplicity: +** No multicast query snooping needed, only multicast report snooping +** No state for querier
_Disadvantages:_
- * Multicast report overhead for every node (both throughput and memory) - * Might cause issues for switches if more than 4k hosts on the network: Usually the MAC table of hardware switches only allows up to 4k clients (there are batman-adv networks with 1.5k hosts already). - * Central querier(s) +* Multicast report overhead for every node (both throughput and memory) +* Might cause issues for switches if more than 4k hosts on the network: Usually the MAC table of hardware switches only allows up to 4k clients (there are batman-adv networks with 1.5k hosts already). +* Central querier(s)
(Yet another simple approach to tackle these disadvantages could be through segmenting the IGMP/MLD domain. The OpenWRT-based firmware framework "Gluon", aiming at wireless community mesh networks, currently has a patchset for this pending: https://github.com/freifunk-gluon/gluon/pull/402)
