Hello Dmitrii:
This is not an OVN error but an error during the router GW port creation. When the router GW port is created in first place, the port host is not assigned yet. This is because the port has not been bound yet. Because of [1], the IPAM module doesn't return any valid subnet and thus the GW port has not fixed IPs on any subnet. This is what you have already described in the definition.
This is because the routed provided networks functionality, that allows to have multiple segments attached to a network, it is supposed to leverage the L3 routing capability of the underlying network. That means the routing processing is done outside Neutron. What Neutron needs to configure is the host segments according to the physical deployment.
In other words, a Neutron router can't be connected as a GW router on a routed provider network. In fact [3] applies only to ML2/OVS. This functionality, as you have seen, doesn't work with ML2/OVN.
Regards.
