IPv6 floating IP ignored in openstack newton

I'm using a public and private network for IPv4 and IPv6 in Openstack Newton. When an instance is created it is given both a private IPv4 and IPv6 address but when I try to associate a IPv6 floating IP I get: Bad floatingip request: Cannot process floating IP association with fe80::8, since that is not an IPv4 address.

I'm using SLAAC for IPv6. I can associate an IPv4 address but not an IPv6 address. I've checked my neutron logs and there is no mention of why IPv6 is being ignored. My endpoint addresses are all IPv4, is this possibly why IPv6 is being ignored? Do I need to add IPv6 endpoints? Thank you for any insight.

There are no floating IPs for IPv6, the assumption is that there is enough public address space available so that you can assign globally reachable addresses to your instances directly instead.

And so an IPv6 address is just added via a network interface to the instance correct?

I have this on an instance right now:

ext-net
2004:4100:a:90:f816:3eff:fe1f:8b18
228.150.73.116

int-net
fc00::f816:3eff:feac:d211
10.0.0.12

but I can't ping the IPv6 address or the IPv4 address. I can only access the instance when I assign a floating IPv4 address to it.
