While the VMware NSX to VMware NSX configuration offers more options, it is still possible to extend Layer 2 networks for prospective VMware Cloud Provider Program customers who have not yet implemented VMware NSX in their on-premises infrastructure. You can enable this by deploying the standalone NSX Edge appliance in the customer’s data center. With the standalone NSX Edge, VMware Cloud Providers can help customers extend on-premises VLANs to VXLAN-backed networks in the VMware Cloud Provider’s hosting environment.

 

In this illustration, the VMware Cloud Provide (on the left) has an NSX Edge gateway appliance configured as the L2VPN server and the customer (on the right) has an NSX Edge gateway appliance configured as the L2VPN client.

This document focuses on the option with no VMware NSX on premises because VMware NSX is a relatively new product for enterprise customers.
