I found that this problem is solved by using OVN version 2.13 in the ovn_controller container. 
This is not a bug of neutron.

Title:
  ARP requests from ovnmeta namespaces are sent to physical interfaces
  of compute nodes

Status in neutron:
  Invalid

Bug description:
  ARP requests from the ovnmeta namespace are sent to the physical
  interfaces of the compute nodes, and then get into the arp tables of
  the network switches. Such requests come to the switches from each
  compute node and cause problems on the switches.

  I have attached a file with packet captures from each interface, a
  list of flows from the required datapath, the output of ovs-vsctl and
  the output of the 'ip address' command from the ovnmeta namespace.

  The cluster has 3 controllers on KVM virtual machines and 8 compute
  nodes on bare metal.

  Version:
  OpenStack Train
  Rocky Linux 8.5, 4.18.0-348.23.1.el8_5.x86_64
  TripleO using the current-tripleo-rdo tag for containers and RPMs
  Open vSwitch 2.15.0-94 on host (from RPM repository NFV)
  OVN 2.12.0-10 in container
