Justin, Thanks. I will post the question to Neutron mailing list.

This is really more a question of how Neutron is configuring OVS than how OVS works. Here's a page that shows how Neutron wires things up: http://docs.openstack.org/grizzly/openstack-network/admin/content//under_the_hood_openvswitch.html You'll probably have better luck posting your question about how multicast works in Neutron on a Neutron mailing list. --Justin On Dec 10, 2013, at 8:57 PM, Taurus Cheung <taurus.che...@harmonicinc.com> wrote: > 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.
