Step 1: Use Direct Connect or VPN to Communicate at Layer 3

Scenarios

An enterprise switch establishes a Layer 2 network based on a Layer 3 network between an on-premises data center and a VPC. This section describes how to create a Direct Connect or VPN connection between an on-premises data center and a VPC at Layer 3.

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 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.
