A provider (external) network bridges instances to physical network infrastructure that provides layer-3 services. In most cases, provider networks implement layer-2 segmentation using VLAN IDs. A provider network maps to a provider bridge on each compute node that supports launching instances on the provider network. You can create more than one provider bridge, each one requiring a unique name and underlying physical network interface to prevent switching loops. Provider networks and bridges can use arbitrary names, but each mapping must reference valid provider network and bridge names. Each provider bridge can contain one flat (untagged) network and up to the maximum number of vlan (tagged) networks that the physical network infrastructure supports, typically around 4000.
Creating a provider network involves several commands at the host, OVS, and Networking service levels that yield a series of operations at the OVN level to create the virtual network components. The following example creates a flat provider network provider using the provider bridge br-provider and binds a subnet to it.
On each compute node, create the provider bridge, map the provider network to it, and add the underlying physical or logical (typically a bond) network interface to it.
# ovs-vsctl --may-exist add-br br-provider -- set bridge br-provider \
protocols=OpenFlow13
# ovs-vsctl set open . external-ids:ovn-bridge-mappings=provider:br-provider
# ovs-vsctl --may-exist add-port br-provider INTERFACE_NAME
Replace INTERFACE_NAME with the name of the underlying network interface.
Note
These commands provide no output if successful.
On the controller node, source the administrative project credentials.
On the controller node, create the provider network in the Networking service. In this case, instances and routers in other projects can use the network.

The value of --provider-physical-network must refer to the provider network name in the mapping.
The OVN mechanism driver and OVN perform the following operations during creation of a provider network.
The mechanism driver translates the network into a logical switch in the OVN northbound database.

If using DHCP to manage instance IP addresses, adding a subnet causes a series of operations in the Networking service and OVN.
The OVN mechanism driver and OVN perform the following operations during creation of a subnet on the provider network.
If the subnet uses DHCP for IP address management, create logical ports ports for each DHCP agent serving the subnet and bind them to the logical switch. In this example, the subnet contains two DHCP agents.
