Multicast on OpenStack

The following works with Neutron VLAN provider networks, and requires configuration on the physical switches. Multicast works on br-int because the ML2 OVS driver/agent uses OVS in standalone mode (no external controller). The packets on br-int hit the NORMAL flow action, and so get treated by the ovs-vswitchd code that does IGMP snooping (when enabled). All IGMP packets are sent to the slow path (userspace ovs-vswitchd).

The following will not work on Neutron tunnel backed networks (VxLAN, GRE), as the neutron-openvswitch-agent hardcodes flows on br-tun that treats multicast the same as broadcasts and the NORMAL action is not used.
