An external device managed by NDFC must have it's role changed to edge router. This action needs to be performed here for your Ext-Rtr to leverage the external connectivity provisioning automation so that the correct configuration is applied based on the best practice templates.

Step 1 - Set External Router Role

Set the role of the external device, Ext-Rtr, correctly:

1. Click Switches
2. Locate and select the checkbox for Ext-Rtr
3. Click Actions
4. Click Set Role in the dropdown menu

5. In the Select Role popup, click Edge Router
6. Then click Select

7. Click Ok in the warning popup that informs that you must perform a Recalulate and Deploy.

Step 1 - Review External Router Role

Review the switch role you set. Again, each switch role will serve a purpose in the type and amount of exact configuration required to be deployed to a given switch, in this case, an external device.

Continue to the next section for the initial Recalculate and Deploy from NDFC to your ExtL3 fabric.
