[Bug 1588593] Re: If Neutron IPAM driver is setted，using 'net-delete' command to delete the network created when ipam_driver is not set，the command seems to cause dead loop.
We never really provided an official migration. Some vendors like
InfoBlox have an unofficial one in order to facilitate migrating to
their drivers. The reason for this is that the internal driver doesn't
provide any advantage over the non-pluggable implementation. It is
effectively equivalent.
We are planning a unconditional migration in Newton so that the built-in
implementation will be removed entirely. I would sit tight

Title:
If Neutron IPAM driver is setted，using 'net-delete' command to delete
the network created when ipam_driver is not set，the command seems to
cause dead loop.
Status in neutron:
Won't Fix
Bug description:
In Mitaka,
When ipam_driver is not setted,created a network with a subnet,then using the reference implementation of
Neutron IPAM driver by setting 'ipam_driver='internal'',and using 'net-delete' command to delete the
network created when ipam_driver is not set，the command seems to cause dead loop.
1)Specifying ‘ipam_driver = <None>’ in the neutron.conf file，created a network with a subnet

3)Deleting the network returns none,and dead.,
the usage of neutron-server is above 80%，and neutron-server's log is repeating “ERROR neutron.ipam.drivers.neutrondb_ipam.driver [req-fd43f9e3-9423-41bc-8434-7787bab0f263 admin 69fa49e368d340679ab3
