Description of problem: Packets with 224.0.0.x should not be forwarded through router even mcast_flood and relay set. Version-Release number of selected component (if applicable): since the feature relay and flood was included. How reproducible: always Steps to Reproduce: topo: (receiver) -- TS1 -- LR (relay=true) -- LS2 -- (sender) # ovn-nbctl show switch cc5a80c8-c520-4942-b9ba-2ec053ea6b52 (ts1) port ts1-lr1 type: remote addresses: ["aa:aa:aa:aa:aa:01 169.254.100.1/24"] port ts1-lr2 type: router router-port: lr2-ts1 switch 8f7f9c2b-4b87-42a5-b2bf-0c469568aec3 (ls2) port ls2-lr2 type: router addresses: ["00:00:00:00:02:00"] router-port: lr2-ls2 port ls2p1 addresses: ["00:00:00:00:02:01 172.16.2.1 172:16:2::1"] port ls2p2 addresses: ["00:00:00:00:02:02 172.16.2.2 172:16:2::2"] router 537c45e9-0e43-4e55-b011-7091c92793cc (lr2) port lr2-ts1 mac: "aa:aa:aa:aa:aa:02" networks: ["169.254.100.2/24"] gateway chassis: [hv1] port lr2-ls2 mac: "00:00:00:00:02:00" networks: ["172.16.2.254/24", "172:16:2::a/64"] then, config as below: ovn-nbctl set logical_switch ls2 other_config:mcast_snoop="true" other_config:mcast_flood_unregistered="true" ovn-nbctl set logical_router lr2 options:mcast_relay="true" ovn-nbctl set logical_router_port lr2-ts1 options:mcast_flood="true" Actual results: send multicast with ip 224.0.0.1 from sender to receiver, receiver can get the packets. but 224.0.0.x should not be forwarded through router. Expected results: 224.0.0.x should not be received by receiver. Additional info:
