Although the external network is an existing network, we still need to define the objects of the external network in Neutron so that router knows how to connect the tenant network to the external network.

In the previous section we have configured the ML2 for creating the external network, and this section will create the ext_net through the UI.

Go to the Admin-Networks menu and click on the "Create Network" button.

The Create page is displayed.

Provider network Type Select "Flat" Physical network to fill in "external", and Ml2_conf.ini parameter settings are consistent . Tick the External Network selection box. Click "Create Network" to create a successful ext_net.

Click on the Ext_net link, go to the Network Configuration page, there is no subnet, click the "Create Subnet" button.

Create a SUBNET_10_10_10_0,IP address of 10.10.10.0/24.

Here Gateway we use the default address 10.10.10.1. Usually we need to ask the network administrator for the gateway IP of the extranet subnet, and then fill it in here.

Click "Next".

Because we do not assign an extranet IP directly to instance, you generally do not need enable DHCP.

Click "Create".

Subnet created successfully, the gateway is 10.10.10.1.

Below is a look at the changes in the control node network structure, performing BRCTL show

Added a bridge brqe496d3d2-53, the physical NIC Eth2 already connected to the bridge.

In the next section we will connect the ext_net to the router and verify the connectivity of the Intranet, as well as the underlying principles of the analysis.
