Description

So far, multicast destinations with mac-addresses 01:00:5E:xx:xx:xx (ipv4-multicast) and 33:33:xx:xx:xx:xx (ipv6-multicast) get broadcasted over the whole mesh network. Every node should be able to learn which hosts joined or left a multicast group by snooping on IGMP (for IPv4) and MLD (for IPv6). BATMAN-nodes should then be able to reduce the overall bandwidth created by multicasts as they could be directed to their destinations.
