Title:
Unable to trigger IPv6 Prefix Delegation
Status in neutron:
Expired
Bug description:
Follow the guide:
https://docs.openstack.org/neutron/pike/admin/config-ipv6.html#configuring-the-dibbler-server
I run devstack and configure Dibber server. But I've checked I could
not trigger the PD process.
Base OS: Ubuntu 18.04
