Description Maciej Józefczyk 2020-04-23 11:38:07 UTC

In Neutron with OVN as a backend we would like to support Routed Provider Networks [1]. This effort is tracked in [2].

With OVS/OVN community we decided to add for multiple localnet ports within one Logical Switch - [3] [4].

This bugzilla is to track this effort in Core OVN.
