[Bug 1372481] [NEW] Neutron doesn't allocate IP to subnet IPv6 stateless when it's combined with others subnets
Public bug reported:
Create network and 4 subnets in it - IPv4 subnet, IPv6 with all kinds of attributes - DHCP stateless, DHCP stateful, DHCP SLAAC.
Create port in this network. It gets IPs only from 3 networks. It should get IP from all 4 subnets.
Scenario:
neutron net-create netto
neutron subnet-create --ip-version 6 --ipv6-ra-mode slaac --ipv6-address-mode slaac netto 2001::/64
neutron subnet-create --ip-version 6 --ipv6-ra-mode dhcpv6-stateless --ipv6-address-mode dhcpv6-stateless netto 2002::/64
neutron subnet-create --ip-version 6 --ipv6-ra-mode dhcpv6-stateful --ipv6-address-mode dhcpv6-stateful netto 2003::/64
neutron subnet-create --ip-version 4 netto 10.10.22.0/24
neutron port-create netto

As you see only 3 IPs are allocated
