Comment 1 for bug 1918108

Hi Pedro,

Thanks for reporting this.

Perhaps is something we need to include in the OVN driver itself. We have this bug downstream at https://bugzilla.redhat.com/show_bug.cgi?id=1933990#c3, and in talks with the Core OVN developers turns out we could enable "mcast_flood_reports" on the Logical_Switch_Ports in the OVN driver to workaround this problem (that would prevent ovn-controller trapping the IGMP pkts).

If you can't wait and want to test it on your environment, it's possible to set this option on the LSP running:

$ ovn-nbctl set logical_switch_port <Neutron port UUID> options:mcast_flood_reports=true
