Public bug reported:

Reported at: https://bugzilla.redhat.com/show_bug.cgi?id=1939468

Neutron does not make sure the router attached logical ports are
provider networks before enabling the send_periodic flag on the
ipv6_ra_config row. This leads the RAs the ovn-controller generates for
tenant networks to leak out against the DC network via the provider
network.

The relevant code is:
https://opendev.org/openstack/neutron/src/branch/master/neutron/plugins/ml2/drivers/ovn/mech_driver/ovsdb/ovn_client.py#L1021.
The code confirms there's no type check happening, the only statement is
making sure IPv6 is enabled and either SLAAC or DHCPv6 are being used.
