Starting with OVN version v21.12.0, OVN replies to ARP requests for ports
that are in a DOWN status. It does not reply in versions older than
v21.12.0. In order to keep the same behavior in Neutron, the default OVN
behavior is overridden by Neutron and Neutron ports will no longer reply to
ARP packets if the ports are in a DOWN state. If it is required to reply to
ARP for such ports, the config option ``ignore_lsp_down`` from
``[ovn_nb_global]`` section can be set to True in the Neutron config. It is
set to False by default.
