Fix sent for review: http://patchwork.ozlabs.org/project/ovn/list/?series=263327&state=* Hi,
I am sorry I can't reproduce it on version:ovn2.13-20.12.0-178.el8fdp.x86_64 and ovn-2021-21.06.0-29.el8fdp
# ovn-nbctl show

then join group 224.1.1.1 from ls1p1,and send traffic from ls2p1 to ls1p1. works fine!
Can you help me with it?
I talked with dceara,my test is right for this bug. so set verified. Right, sorry for the late notice, the test looks good to me, thanks!

Description of problem: When IP multicast relay is enabled on a logical router that contains distributed gateway ports, multicast traffic is not forwarded correctly on the distributed gateway port. Version-Release number of selected component (if applicable): ovn21.09-21.09.0-18.el8fdp ovn2.13-20.12.0-178.el7fdp How reproducible: Always. Steps to Reproduce: # Logical network: # Two logical switches (sw1-sw2) connected to a logical router (rtr). # with distributed gateway ports configured towards the logical switches. # sw1: # - subnet 10.0.0.0/8 # - 1 ports bound on hv1 (sw1-p1) # sw2: # - subnet 20.0.0.0/8 # - 1 port bound on hv2 (sw2-p2) # - IGMP Querier from 20.0.0.254 ovn-nbctl ls-add sw1 \ -- lsp-add sw1 sw1-p1 ovn-nbctl ls-add sw2 \ -- lsp-add sw2 sw2-p2 ovn-nbctl lr-add rtr \ -- lrp-add rtr rtr-sw1 00:00:00:00:01:00 10.0.0.254/24 \ -- lrp-add rtr rtr-sw2 00:00:00:00:02:00 20.0.0.254/24 ovn-nbctl lsp-add sw1 sw1-rtr \ -- lsp-set-type sw1-rtr router \ -- lsp-set-addresses sw1-rtr 00:00:00:00:01:00 \ -- lsp-set-options sw1-rtr router-port=rtr-sw1 ovn-nbctl lsp-add sw2 sw2-rtr \ -- lsp-set-type sw2-rtr router \ -- lsp-set-addresses sw2-rtr 00:00:00:00:02:00 \ -- lsp-set-options sw2-rtr router-port=rtr-sw2 ovn-nbctl lrp-set-gateway-chassis rtr-sw1 hv1 10 ovn-nbctl lrp-set-gateway-chassis rtr-sw2 hv2 10 # Bind sw1-p1 to an OVS port on hypervisor hv1. # Bind sw2-p2 to an OVS port on hypervisor hv2. # Send an IGMP join on sw2-p2, e.g., with iperf: iperf -s -B 224.3.3.3 -u -T 2 -t 3000 -i 5 # Send IP multicast traffic on sw1-p1, e.g., with iperf: iperf -c 224.3.3.3 -u -T 2 -t 3000 -i 5 Actual results: Traffic doesn't get properly tunneled (geneve) from hv1 to hv2 and is not delivered to sw2-p2. Expected results: Traffic should be tunneled between hv1 and hv2 and then delivered to sw2-p2. Additional information: This breaks IP multicast functionality in ovn-kubernetes since https://github.com/ovn-org/ovn-kubernetes/commit/09af6537438fe6a244e057b0d318bff08b00d6b7
