Hello! I want to ask about patch for MAC_binding functionality, seems that it just adding but not updating or deleting MAC_Bindig rows.
https://github.com/ovn-org/ovn/commit/a2b88dc5136507e727e4bcdc4bf6fde559f519a9 In my setup I have logical router with DNAT rules. Whenever I create or delete logical routers or DNAT rules on them with same IPs, I can see that MAC_Binding rows are not updated or deleted in SBDB. Let me show some example of relationships between Port_Binding and Mac_Binding, which I expect to be properly served by OVN controller pinctrl module. But its not :( - DNAT rule added Port_Binding _uuid : 7c16e012-5acc-498e-b656-79a19f5bb4d1 chassis : 1f4aa70f-804a-4e98-b8ba-22db389be1e2 datapath : 09b37624-d7d2-4a21-8758-3809ae319f62 encap : [] external_ids : {"neutron:cidrs"="10.14.0.253/24", "neutron:device_id"="9788b99d-351c-4741-92d3-2ee27ecd1e3f", "neutron:device_owner"="network:router_gateway", "neutron:network_name"=neutron-a0f9f5fd-e94b-44d9-a4b3-66082dd9dd5a, "neutron:port_name"="", "neutron:project_id"="", "neutron:revision_number"="1", "neutron:security_group_ids"="", "neutron:subnet_pool_addr_scope4"="", "neutron:subnet_pool_addr_scope6"=""} gateway_chassis : [] ha_chassis_group : [] logical_port : "ad363382-c4e1-42f1-a103-85a0decf8b73" mac : [router] nat_addresses : ["fa:16:3e:a1:d9:1e 10.14.0.250"] <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< This field updated!!!

The same picture I can see when, some DNAT rules were added to first router then router deleted and then DNAT rules repeated on second router with same IPs - traffic blackholed again. My setup: - OVN 22.03.3 - OVS 2.17.7 Could some one approve my assumptions about lack of update/delete MAC bindings mechanism in OVN controller in 22.03? Also I appreciate any suggestions about this problem! BR Artem УВЕДОМЛЕНИЕ О КОНФИДЕНЦИАЛЬНОСТИ: Это электронное сообщение и любые документы, приложенные к нему, содержат конфиденциальную информацию.
