Hi,

Do you know why Neutron <-> OVN DB sync code synchronizes "DEVICE_OWNER_ROUTER_HA_INTF" router ports here in this line: https://github.com/openstack/neutron/blob/164f12349fd8be09b9fd4f23b8cf8d2f3eccd11b/neutron/plugins/ml2/drivers/ovn/mech_driver/ovsdb/ovn_db_sync.py#L460 ?

As far as know there is no need for HA network ports for L3 virtual routers implementation in OVN, because OVN uses the internal BFD mechanism for Gateway Chassis reachability tests.

Thanks,

Piotr
