requirements of VIM-agnostic IPv6 functionality, including infrastructure layer and VNF
(VM) layer, and its gap analysis with OpenStack Neutron in Kilo Official Release.

-|=====================================+============+===============================================+
-|All topologies work in a multi-tenant|Yes |The IPv6 design is following the Neutron tenant|
