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. ** Affects: neutron Importance: High Assignee: Lucas Alvares Gomes (lucasagomes) Status: Confirmed ** Tags: ovn ** Tags added: ovn ** Changed in: neutron Importance: Undecided => High ** Changed in: neutron Status: New => Confirmed ** Changed in: neutron Assignee: (unassigned) => Lucas Alvares Gomes (lucasagomes) -- You received this bug notification because you are a member of Yahoo!
