[openstack-dev] [Neutron][IPv6] Neutron IPv6 in Icehouse and further

Hello Maksym,

last week I had more or less the same questions than you and I investigate
a little bit... Currently we have the *ipv6_ra_mode *and *ipv6_address_mode
*in the subnet entity. The way you combine these two values will determine
how and who will configure your VM´s IPv6 addresses. Not all the
combinations are possible. This document[1] and the *upstream-slaac-support*
 *spec*[2] provide the possible combinations. Not sure which one is more

If you want to try IPv6 current support, you can use the Baodong Li's
devstack patch [3], although is still in development. Follow the message
commit instructions to provide a radvd daemon. That means that there is no
RA advertiser in Neutron currently. There is a *spec* in review[4] to fill
this gap.

The changes for allow DHCPv6 in dnsmasq are in review in this patch[5].

This is what I found... I hope some IPv6 folks can correct me if this
information is not accurate enough (or wrong)
