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")

        Bridge br-int

        Port "qvo128d8126-0c"

            tag: 1

            Interface "qvo128d8126-0c"

        Port "qvof11a3165-a5"

            tag: 2

            Interface "qvof11a3165-a5"

        Port "qvo0cf1ef19-80"

            tag: 1

            Interface "qvo0cf1ef19-80"

        Port "qvo48fdea98-df"

            tag: 2

            Interface "qvo48fdea98-df"

        Port br-int

            Interface br-int

                type: internal

        Port "qvo191216ce-02"

            tag: 2

            Interface "qvo191216ce-02"

        Port "qvo5de83fb2-d4"

            tag: 2

            Interface "qvo5de83fb2-d4"

        Port "int-br-eth1"

            Interface "int-br-eth1"

    Bridge "br-eth1"

        Port "eth1"

            Interface "eth1"

        Port "br-eth1"

            Interface "br-eth1"

                type: internal

        Port "phy-br-eth1"

            Interface "phy-br-eth1"

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.

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?
