Prerequisites

You have planned the resources required both on the cloud and on premises. For details about resource planning, see How Enterprise Switches Work.

Procedure

1. Create a Direct Connect or VPN connection.

   For details, see the Direct Connect User Guide or Virtual Private Network User Guide.

   

   Only classic VPNs can be used together with enterprise switches.

2. Submit a service ticket to check whether your Direct Connect or VPN connection supports VXLAN interconnection with an enterprise switch. If your connection does not support this, contact customer service.
