Hi ,
Could anyone please check the bug below?
https://bugs.launchpad.net/neutron/+bug/1467791


This bug description:
When the created network contains one ipv4 subnet and an ipv6 subnet which turned on slaac or stateless.
When I create a port use cmd like:
neutron port-create --fixed-ip subnet_id=$[ipv4_subnet_id] $[network_id/name]
The specified fixed-ip is ipv4_subnet, but the returned port contained the ipv6 subnet.




If user just want a port with ipv4 , why returned port had allocated an ipv6 address.
And I know this is an design behavior from http://specs.openstack.org/openstack/neutron-specs/specs/kilo/multiple-ipv6-prefixes.html#proposed-change
But we are still confused about this operation.


Thank you anyone could help for confirm this issue , and wish you return the message asap.
