The initial deployment to the Core Router device in your ISN 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 Core Router

At the top right of the ISN 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 ISN fabric core device.

1. In the bottom right, click Deploy All

Step 3 - Exit Deploy Configuration

Upon a successful deployment, Nexus Dashboard'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, Nexus Dashboard 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 - Return to 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

Summary

You deployed the initial configuration to the ISN core router, including the loopback and base connectivity settings. With all three fabric types now deployed and in-sync (Site1 VXLAN, ExtL3, and ISN), you have the foundation in place for Multi-Site connectivity. Nexus Dashboard managed the entire infrastructure buildout through a consistent, repeatable workflow.
