Hi Harm:

The changes for the multiple v6 addresses blueprint depend upon 2 Neutron 
changes that are not in Icehouse, but are merged in the latest upstream:
https://blueprints.launchpad.net/neutron/+spec/ipv6-two-attributes
https://blueprints.launchpad.net/neutron/+spec/ipv6-provider-nets-slaac

Also, if you want to use IPv6 SLAAC addresses assigned by Neutron (via RADVD), 
you'll want some changes for the following blueprint, that are not in Icehouse 
but are in the latest upstream:
https://blueprints.launchpad.net/neutron/+spec/neutron-ipv6-radvd-ra

If you want to use DHCPv6 stateful addresses assigned by Neutron, I believe 
that you'll need the changes from this blueprint that are still out for review:
https://blueprints.launchpad.net/neutron/+spec/dnsmasq-ipv6-dhcpv6-stateful

Hi Dane,

Thanks, that looks promising. Once support for multiple v6 addresses on gateway 
ports is added I'll be happy to give this a go. Should it work just fine with 
an otherwise Icehouse based deployment?

Regards,
Harm
