Was verified on puddle RHOS-16.1-RHEL-8-20210120.n.1 with python3-networking-ovn-7.3.1-1.20201114024050.el8ost.noarch
Verified that igmp snooping works properly on external and internal networks, no flooding to all ports of logical switch, only to the ports that have subscribed clients behind them.
Addition to the previous comment. For proper work an external igmp querier is required. Otherwise clients will not remain subscribed after idle timeout, 300 seconds by default. For internal networks the external querier can not be used. There is an option to enable an internal querier in OVN, see , but it is still not officially supported.
