thanks for having a look into this issue. I could see in my experiments that the loop starts when an OpenStack router is configured with an external gateway network. After a port is attached to the router, we see the behavior described above. Maybe it is important to mention that in our lab setup we have a flat provider external network, with two gateway nodes, both of which are configured in OVN with enable-chassis-as-gw in ovn-cms-options.
If it still does not reveal the issue, I will make a clean reproducing setup today or tomorrow and will share it with you.
