commit 5d21998524514c0cab6a40e7fa415d9ff6a88f4a Author: Slawek Kaplonski <skapl...@redhat.com> Date: Thu Dec 10 00:10:38 2020 +0100 Fix multicast traffic with IGMP snooping enabled In the ML2/OVS when igmp_snooping is enabled but there is no external querier multicast traffic will stop working after few minutes as packets will not be flooded to tunnel/external bridges. So this patch sets "mcast-snooping-disable-flood-unregistered" option of the br-int to False (default value) even when igmp_snooping is enabled in the neutron-ovs-agent's config file. Additionally it configures "mcast-snooping-flood-reports" and "mcast-snooping-flood" on patch ports in br-int to True. That way we can provide best effort snooping: multicast isolation where IGMP queriers are available and flood everywhere else?
