Public bug reported:

When VMs associated to a provider network, with disabled port security,
try to reach IPs on the provider network not known by OpenStack, there
is a flooding issue due to FDB table not learning MACs. It seems there
is a option in ovn [1] to address this issue but it is not used by
OpenStack.
