I checked current neutron code in stable/queens and see that when dvr is connected to a subnet, it installs filter rule about arp going for subnet gateway. neutron/plugins/ml2/drivers/openvswitch/agent/ovs_dvr_neutron_agent.py ~~~ 346 def _bind_distributed_router_interface_port(self, port, lvm, 347 fixed_ips, device_owner): ... 418 # TODO(vivek) remove the IPv6 related flows once SNAT is not 419 # used for IPv6 DVR. 420 if ip_version == 4: 421 if subnet_info['gateway_ip']: 422 br.install_dvr_process_ipv4( 423 vlan_tag=lvm.vlan, gateway_ip=subnet_info['gateway_ip']) <===HERE 424 else: 425 br.install_dvr_process_ipv6( 426 vlan_tag=lvm.vlan, gateway_mac=subnet_info['gateway_mac']) 427 br.install_dvr_process( 428 vlan_tag=lvm.vlan, vif_mac=port.vif_mac, 429 dvr_mac_address=self.dvr_mac_address) ~~~ Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
