Hello all, I faced issue, when booting instance from shared external network, designate did not create DNS records. So I looked deeper and find, that issue are in networks router:external to True. But in DNS extension code I did not get why such feature, are restricted: https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/extensions/dns_integration.py#L296 Can someone with deeper knowledges describe why to allow create DNS records in network with router:external are bad behavior? I don't see a point to create DNS record with router:external if shared are to False, but if it is True, I don't see any particular issues. Best regards, Martins
