There are several scenarios in which Virtual Machine can be created on provider networks.
| Provider Network (Physnet) | VLAN Provisioning by ML2 | 
|---|---|
| default | VLAN provisioning of endpoints is done when Neutron ports are
                                bound to a host or compute node. Example: 
 | 
| default (device-owner=dc-edge –host=<DCGW>) | VLAN provisioning for default physnet is done during port creation based on additional parameters passed during port create call. | 
| non-default (PFPT_L, EXT1) | VLAN provisioning is done during network creation or segment creation of single segment or multiple segment. | 
The endpoints are deprovisoned during the following negation operations:
