<div>Hi,</div>
<div><br>
</div>
<div>There is a patch for radvd <a href="https://review.openstack.org/#/c/102648/2">https://review.openstack.org/#/c/102648/2</a> that you can use in addition to the devstack patch. You want to make sure that ipv6 is enabled and ra accepted with your VM’s image.
Both patches are under development.</div>
<div><br>
</div>
<div>To use dhcpv6, the current dhcp agent should be working. However, it might be broken due to a recent commit. If you found a Traceback in your dhcp agent log complaining about an uninitialized reference to the variable ‘mode', you may hit that issue. You
can just initialize it to be ‘static’. In addition, only recently, dhcp messages maybe dropped before entering the VM. Therefore, you might need to disable the ipv6 rules manually by “ip6tables –F” after a VM is launched . Also make sure you are using the
latest dnsmasq (2.6.8)</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Robert</div>

<div class="gmail_default" style="font-family:tahoma,sans-serif">last week I had more or less the same questions than you and I investigate a little bit... Currently we have the
<i>ipv6_ra_mode </i>and <i>ipv6_address_mode </i>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
<i>upstream-slaac-support</i> <i>spec</i>[2] provide the possible combinations. Not sure which one is more updated...</div>

<div class="gmail_default" style="font-family:tahoma,sans-serif">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 <i>spec</i> in review[4] to fill this gap.</div>

<div dir="ltr">Hi! I'm waiting for that too...
<div><br>
</div>
<div>Currently, I'm running IceHouse with static IPv6 address, with the topology "VLAN Provider Networks" and, to make it easier, I'm counting on the following blueprint:</div>

<div>...but, I'm not sure if it will be enough to enable basic IPv6 support (without using Neutron as Instance's default gateway)...</div>

<div><br>
</div>
<div>Could you please tell what is the current state of IPv6 in Neutron? Does it have DHCPv6 working?</div>
<div><br>
</div>
<div>What is the best point to start hacking from? Devstack stable/icehouse or maybe some tag? Are there any docs / raw deployment guides?</div>
<div>I see some patches not landed yet [1] ... I assume it won't work without them, right?</div>
