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.
|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 deprovisioned during the following negation operations:
The ML2 driver supports overlapping VLAN across provider physical networks.
