OpenStack Networking (Neutron)
114ca0f1be
Prior to this patch, ML2/OVS and ML2/OVN had inconsistent IGMP configurations. Neutron only exposed one configuration option for IGMP: igmp_snooping_enabled. Other features such as IGMP flood, IGMP flood reports and IGMP flood unregistered were hardcoded differently on each driver (see LP#2044272 for a more details). These hardcoded values has led to many changes over the years tweaking them to work on different scenarios but they were never final because the fix for one case would break the other. This patch introduces 3 new configuration options for these other IGMP features that can be enabled or disabled on both backends. Operators can now fine tune their deployments in the way that will work for them. As a consequence of the hardcoded values for each driver we had to break some defaults and, in the case of ML2/OVS, if operators want to keep things as they were before this patch they will need to enable the new mcast_flood and mcast_flood_unregistered configuration options. That said, the for ML2/OVS there was also an inconsistency with the help string of igmp_snooping_enabled configuration option as it mentioned that enabling snooping would disable flooding to unregistered ports but that was not true anymore after the fix [0].
