Overview

An HPE network virtualization controller can use the Open vSwitch Database (OVSDB) management protocol to deploy and manage VXLANs on VTEPs. To work with a controller, you must configure the VTEP as an OVSDB VTEP.

As shown in Figure 24, an OVSDB VTEP stores all of its VXLAN settings in the form of entries in an OVSDB database. The OVSDB database, OVSDB VTEP service, and the controller interact through the OVSDB server. The controller communicates with the OVSDB server through the OVSDB protocol to manage the OVSDB database. The OVSDB VTEP service reads and writes data in the OVSDB database through the OVSDB server.

The OVSDB VTEP service performs the following operations to manage the VXLAN settings on the VTEP:

You can configure a VTEP both at the CLI and through a controller. As a best practice, do not manually remove the VXLAN configuration issued by the controller.
