Public bug reported: Related bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1993681
Patch [1] allowed to have multiple physical networks per bridge. Although this could be feasible in OVN, the ML2 OVN mechanism driver should not allow it. The OVN mech driver should have the same behaviour as OVS or LB. In the related bugzilla there are some steps to reproduce a configuration that leads to a subnet CIDR range conflict, when both networks are in the same bridge, that is not prohibited by Neutron. Steps to Reproduce: 1. Create two physical networks mapped to the same physical network 2. Enable both two physical networks as flat network providers 3. Create a flat network and a subnet with range 10.0.0.0/24 on the first physical network 3. Create another flat network and a subnet with range 10.0.0.0/24 on the second physical network [1]https://github.com/openstack/networking- ovn/commit/a4781fd0f9c59603638b41069a175547a24c4b1c ** Affects: neutron Importance: Low Assignee: Rodolfo Alonso (rodolfo-alonso-hernandez) Status: New ** Changed in: neutron Assignee: (unassigned) => Rodolfo Alonso (rodolfo-alonso-hernandez) ** Changed in: neutron Importance: Undecided => Low -- You received this bug notification because you are a member of Yahoo!
