Is this your observation? or question? What is your configuration in this
case?

What do you mean by setting gre tunnel to br1? Is this like below: ?
ovs-vsctl add-port br1 gre_br1 -- set interface gre_br1 type=gre
options:remote_ip=<ip address of br1 on the other machine>

If it is, it will not work. Because the machine does not know how to get to
"ip address of br1 on the other machine".

Kind Regards,
Alex Wang,
