It does seem like you are getting both a local address (fd00::1:0:4) and a possibly valid address (fe80::7cea:d7ff:fe95:31c).
Presumably the latter is via auto-discovery?
Or is it being defined in MAAS?
Can you give a little bit more information about your configuration? (have you tried deploying the applications by themselves rather than all of openstack to make it a bit easier to reproduce?)
We'd also need how you're configuring the nodes in MAAS.
