Setup:

• Neutron/ML2 ODL master
• ODL Lithium 0.3.0-SNAPSHOT

Pre-conditions:

• neutron net-create test
• neutron subnet-create test --name s1 10.0.0.0/22
• neutron subnet-create test --name s2 20.0.0.0/22

At this point I have provisioned my resources, a DHCP port will be allocated and will have two IP allocations one for each subnet.

Steps to reproduce:

neutron subnet-delete s1

Observed:

I see that an HTTP Conflict is r returned by ODL, the DHCP port is deleted entirely.

I can then, without errors delete the other subnet and the network.

If I try to delete s2 first, I won't see the error, the DHCP port disappears, but when I try to delete s1 I still see the conflict error being returned.

One more data point. If I delete the network directly, no errors are being returned.
