ovs rstp_designated_path_cost for GRE

In proxmox documents I can see it's advised to set rstp_designated_path_cost for physical ports, but as I want to create a mesh network with openvswitch containing 20 nodes which all are connected together via GRE is it necessary to set path_cost for GRE too?
I've tried command below but it didnt change anything
ovs-vsctl set Port gre-c11 other_config:rstp_designated_path_cost=20000
vs-vsctl get Port gre-c111 rstp_status
{rstp_designated_bridge_id="8.000.6aafb64b7d49", rstp_designated_path_cost="0", rstp_designated_port_id="8002", rstp_port_id="8001", rstp_port_role=Alternate, rstp_port_state=Discarding}
According to this mail the value shown in 'vs-vsctl get Port gre-c111 rstp_status' is not the cost you just set.
You can check '/etc/openvswitch/conf.db' to see the effect of your 'set' command.
