Quick Start

Enterprise switches establish a Layer 2 network between on-premises data centers and VPCs based on the Layer 3 network established by VPN or Direct Connect. Figure 1 shows the configuration process of enterprise switches.

No.	Step	Description
1	Step 1: Use Direct Connect or VPN to Communicate at Layer 3	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 aDirect Connect or VPN connection between an on-premises data center and a VPC at Layer 3.
2	Step 2: Buy an Enterprise Switch	This section describes how to buy an enterprise switch. An enterprise switch allows Layer 2 communication between an on-premises data center and a VPC based on VPN or Direct Connect.
3	Step 3: Create a Layer 2 Connection	After an enterprise switch is created, you need to create a Layer 2 connection to enable the local Layer 2 connection subnet and the remote VXLAN switch to communicate at Layer 2.
4	Step 4: Configure a Tunnel Gateway in Your Data Center	This section describes how to configure the tunnel gateway on a VXLAN tunnel switch of an on-premises data center.
