According to our roadmap, we have successfully accomplished our Phase 1 Work in Brahmaputra Release covering the design and implementation of IPv6 vRouter using service VM in native OpenStack environment and ODL-integrated environment.
In Phase 2, we are planning the following features for C Release:
At underlay level, multiple instances of OpenStack can be deployed at multisites, one at each site, and use IPv6 for normal Neutron Router
At overlay level, the simplest case is that vRouter is deployed at multisites, each vRouter at each site, and connects to ext-net that has physical IPv6 router. Then vRouters at multisites can communicate with each other (North-South). Thus VM on each subnet can communicate with IPv6 packets via North-South connectivity.
Then there are HA related issues, including both multisite and standalone deployment.
No resource available. Postponed to D Release or later
