ipv6 floating Ip is currently not supported. Check out this review and the associated bug: https://review.openstack.org/#/c/131145/

Just saw there is a summit talk about it called IPv6 Feature in Openstack Juno. Dual stack floating ip support is planned in K. However, I couldn't even get single IPv6 floating IP to work. Even though I configured only IPv6 subnet for the external network, I got those errors from neutron-l3-agent when associating the floating IP to instance.

Adding 2 subnets to this external net and creating a gateway to it on the l3 router causes a problem. Do we need to wait for K before we can fully go dual-stack? - Harm op 29-10-14 15:29, Jerry Xinyu Zhao schreef: Hi I want to use both ipv4 and ipv6 for floating ip at the same time.
