The initial deployment to the external device in your ExtL3 fabric in this section will be a small amount of configuration, specifically the BGP routing process with the ASN you input into the External Fabric's Fabric Settings.

Step 1 - Trigger Initial Deployment for Your External Router

At the top right of the ExtL3 fabric, locate the fabric-level Actions button:

1. Click Actions
2. Click Recalculate and Deploy

Step 2 - Deploy Initial Config

In the Deploy Configuration wizard, you can visually see that not many lines of configuration are required to be configured to your ExtL3 fabric external device.

1. In the bottom right, click Deploy All






The stage moves to Deploy Progress where the Out-of-Sync status will change to STARTED while NDFC deploys the device, role specific, configuration. Make note that you can see the progress for the executed number of lines being configured via the progress bar:

Step 3 - Exit Deploy Configuration

Upon a successful deployment, NDFC's Deploy Configuration wizard should look as shown in the screenshot below; all green with SUCCESS messages and each switch's expected configuration progress bar also displaying as green and fully executed. If any error occurred, NDFC will display a notification and the status reverted back to Out-of-Sync.

1. After done reviewing the deployment progress, click Close in the bottom right

Step 4 - Review Switches Overview

Back at the main Switches overview, your Ext-Rtr device should display a Config Status of In-Sync.

Step 5 - Revisit Main Overview Dashboard After Initial Deployment

Revisist the main Overview dashboard and now examine what the dashboard is populated with after initial deployment.

1. Click Overview

Notice the Switch Configuration status and Switch Roles information is updated and in a healthy state. Additionally, the Interfaces area of the dashboard is populated with lots of interfaces. There are many due to the external device being a Nexus 9300v.

Continue to the next section to deploy the VRF Lite external Layer 3 to your Site1-BL1 border leaf in your Site1 fabric.
