[Bug 1631693] [NEW] prefix delegation does not work in newton
Public bug reported:
Using a provider network, set up and tested working as laid out here:
http://docs.openstack.org/newton/install-guide-ubuntu/launch-instance-networks-selfservice.html
Using the prefix delegation as defined here:
http://docs.openstack.org/newton/networking-guide/config-ipv6.html
Neutron tries to add the prefix_delegated network directly as just
'::1/64', which fails.
