Hi Justin,
Configuration details:
1) The 2 VMs are running on the same OpenStack compute node (Grizzly version)
2) Both VMs have a virtual nic to receive multicast traffic in VLAN 1002
3) Openvswitch version is 1.9.0
4) ovs quantum plugin is configured in tenant_network_type vlan
5) The ovs bridge interface is eth1
(output of "ovs-vsctl show")

6) eth1 is physically connected to a Cisco L3 switch. That switch port is a
VLAN trunk port, properly configured in VLAN group 1002. The multicast source
is input from another port on the same switch.

Multicast Source
Our experiment result is "VM-B would not receive the multicast traffic joined
by VM-A".

How's it configured? Did you install any flows or VLANs? Anything else that
may affect configuration?
