Dbridge.rst180 Multicast chapter
183 The Linux bridge driver has multicast support allowing it to process Internet

185 messages, and to efficiently forward multicast data packets. The bridge
188 Multicast snooping
191 Multicast snooping is a networking technology that allows network switches
192 to intelligently manage multicast traffic within a local area network (LAN).
194 The switch maintains a multicast group table, which records the association
195 between multicast group addresses and the ports where hosts have joined these

Dswitchdev.rst180 - VLAN flooding of multicast/broadcast and unknown unicast packets
301 and other IEEE 01:80:c2:xx:xx:xx link-local multicast packets can pass.
310 For a given L2 VLAN domain, the switch device should flood multicast/broadcast
336 The bridge multicast module will notify port netdevs on every multicast group
338 The hardware implementation should be forwarding all registered multicast
431 including multicast, DHCP, IPv4/6, etc. If necessary, it should program the
