[Bug 1365756] [NEW] DHCPv6 stateful doesn't assign IP to ports created before it
Public bug reported:
When we create port in network without subnets(*) and then create IPv4
subnet with DHCP enabled, the port gets IP automatically. Unlike so with
IPv6 subnets. When we create subnet with DHCPv6 stateful the port
doesn't get anything from DHCP server automatically, only after explicit
port-update. It's inconsistence.
With IPv4:
$ neutron net-create netto
$ neutron port-create netto
$ neutron subnet-create --ip-version=4 netto "192.168.111.0/24"
