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

-|Use Case / Requirement |Supported in Kilo Neutron|Notes |
-+=====================================+=========================+=================================+
-|All topologies work in a multi-tenant|Yes |The IPv6 design is following the |
-|environment | |Neutron tenant networks model; |
-| | |dnsmasq is being used inside DHCP|
-| | |network namespaces, while radvd |
-| | |is being used inside Neutron |
-| | |routers namespaces to provide |
-| | |full isolation between tenants. |
-| | |Tenant isolation can be based on |
-| | |VLANs, GRE, or VXLAN |
-| | |encapsulation. In case of |

-| | |(and VTEPs) must be IPv4 based as|

-+-------------------------------------+-------------------------+---------------------------------+
-|IPv6 VM to VM only |Yes |It is possible to assign IPv6- |
-| | |only addresses to VMs. Both |
-| | |switching (within VMs on the same|
-| | |tenant network) as well as east/ |
-| | |west routing (between different |
-| | |networks of the same tenant) are |
-| | |supported. |
