NDFC has various policy templates available to you. These are used in the templates for the provisioning that is automatically occurring when you deploy your VXLAN EVPN fabrics. You can use these policy templates for your own purposes as well to achieve the outcomes you require in your network when deploying or making a configuration change. In this section, we're going to use a BGP network statement template to inject a prefix from your Ext-Rtr into your border leaf, thus into your fabric for testing external connectivity a little later.

Step 1 - Navigate to Policies and Launch Create Policy Wizard

Navigate to Policies to launch the Create Policies wizard and being creating your BGP network statement policy:

1. Click the Policies tab in the top navigation bar
2. Click Actions
3. Click Add Policy

Step 2 - Select Switch

1. Click Ext-Rtr
2. Click Next

Step 3 - Select BGP VRF Network Statement Template

In the Create Policy Policy.

1. Click on No Policy Selected

The Select Policy Template should come up. Search for the correct BGP policy template that provides the configuration for creating a BGP network statement in a VRF instance:

1. In the search field, search bgp_vrf_network
2. Click bgp_vrf_network
3. Click Select

Step 4 - Configure BGP VRF Network Statement Policy

With the correct BGP policy selected to create a network statement in a VRF instance, you must provide configuration parameters that match your deployed external router:

1. Set the BGP AS # to 65333 to match the existing ASN already configured on your Ext-Rtr
2. Set the VRF Name to BlueVRF to match the existing VRF already configured on your Ext-Rtr and in your Site1 VXLAN EVPN fabric
3. Set the IP prefix to advertise to 172.16.1.1/32 to match the Loopback interface you created in the previous section
4. Click Save

Step 5 - Confirm BGP Policy Created

Back at the main Policies overview, locate the policy you created to confirm it is in the list:

1. In the filter box type Template == bgp_vrf_network
2. Confirm the policy you created is present
3. Clear the filter by clicking the to close filter parameter

Continue to the next section to perform the deployment of the Loopback interface and BGP policy you created in the last two sections.
