Comment 1 Chris Fields 2021-01-14 21:16:41 UTC

The procedures in this guide will not persist if openvswitch is restarted.  This is a change in behavior.  See bug https://bugzilla.redhat.com/show_bug.cgi?id=1910304.  

This section should be preceded with a 'NOTE: These procedures will enable multicast snooping immediately, but will not persist after an openvswtich restart. To enable persistent multicast snooping set igmp_snooping_enable via the ComputeExtraConfig Overcloud parameter. This is set-able by flavor as show below:

parameter_defaults:
  ComputeExtraConfig:
    neutron::agents::ml2::ovs::igmp_snooping_enable: True
  ComputeOvsDpdkExtraConfig:
    neutron::agents::ml2::ovs::igmp_snooping_enable: False
  ComputeSriovExtraConfig:
    neutron::agents::ml2::ovs::igmp_snooping_enable: True'
