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

Before using enterprise switches, plan resources on and off the cloud by referring to How Enterprise Switches Work.

Procedure

  1. Create a Direct Connect or VPN connection.

    Select the VPC (vpc-01) where the enterprise switch is created in Step 2: Create an Enterprise Switch.

    For details, see Configuring a Direct Connect Connection or Configuring a VPN Connection.

  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 technical support.
