1	Step 1: Use 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 a VPN connection between an on-premises data center and a VPC at Layer 3.
2	Step 2: Create an Enterprise Switch	This section describes how to create an enterprise switch. An enterprise switch allows Layer 2 communication between an on-premises data center and a VPC based on VPN.
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.
