Hi,
I'm running OVS 2.5.0 @be3f39c94, and I see duplicate multicast packets in the
following scenario.
# ovs-vsctl add-br br0
# ovs-vsctl add-port br0 bond1
# ovs-vsctl set Bridge br0 mcast_snooping_enable=true
# ovs-vsctl set Bridge br0
other_config:mcast-snooping-disable-flood-unregistered=t
When these are OVS patch ports you don’t need to worry about their MTU –
packets don’t actually flow through patch ports. In the past there was an
option to use veth pairs between bridges and there was a parameter called
veth_mtu.

It's not clear that your problem is to do with dropped packets. Your ifconfig is
showing dropped packets for interface vmbr1. This is the internal interface on
bridge vmbr1 - I don't think you are using it. I see the same on my systems that
are working fine.

I don't, but I didn't research other plugins.
With ML2/OVS we used VLAN provider networks and let the physical network manage
multicast between physical nodes.

Thanks Ben. I tested on master and it fixes the mdb problem.
The next problem is that any existing flows don't seem to get updated
or invalidated after the mdb gets another entry for a grou

Yes it does - thanks. But now we have another problem when the video app
restarts. Still trying to pin it down.

Hi,
We have an application that we need to be able to restart quickly. It listens
on a multicast address, so a restart causes IGMPv3 leave packets to be sent and
join packets soon after. OVS250 receives the leave packet and removes the entry
from the mdb, but ignores the join and the entry does
13 matches
