Comment 1 for bug 1513894

Looking at http://docs.openstack.org/mitaka/networking-guide/adv-config-ipv6.html I wonder whether this is really an issue. The usual procedure seems to be to set

ipv6_pd_enabled = True

in neutron.conf which will have the side effect of making the "--use_default_subnetpool" option to automatically set the subnetpool_id to "prefix_delegation".

So what would be the use case where for subnet creation one would need to set the pool_id explicitly instead of using --use_default_subnetpool?
