Created attachment 1729748 [details] multicast script I used for tests Taken from https://github.com/redhat-openstack/nfv-tempest-plugin/blob/master/nfv_tempest_plugin/tests/scenario/tests_scripts/multicast_traffic.py, but I also added a fix to support python3 as well We have a scratch build with this fix, while we obtain the exception permission for 16.1 z4 branch merge. It is located here: http://brew-task-repos.usersys.redhat.com/repos/scratch/ffernand/python-networking-ovn/7.3.1/1.20201114024049.el8ost/noarch/ rsafrono was kind enough to verify the fix in job: https://rhos-ci-jenkins.lab.eng.tlv2.redhat.com/view/DFG/view/network/view/networking-ovn/job/DFG-network-networking-ovn-16.1_director-rhel-virthost-3cont_2comp-ipv4-geneve/107/testReport/neutron_plugin.tests.scenario.test_multicast/MulticastTestIPv4/test_igmp_snooping_same_network_and_unsubscribe_id_9f6cd7af_ca52_4979_89e8_ab7436905712_/ @jmelvin to see if that can be used in the meantime. Verified on puddle RHOS-16.1-RHEL-8-20210120.n.1 with python3-networking-ovn-7.3.1-1.20201114024050.el8ost.noarch Verified that there is no flooding of multicast traffic to all ports of logical switch when there are no subscribed clients. Verified also that igmp snooping works properly when there are subscribed clients.
