controller (OVSDB)


Hierarchy Level


Configure a connection between a Juniper Networks device running the Open vSwitch Database (OVSDB) management protocol and a software-defined networking (SDN) controller. You can connect a Juniper Networks device to more than one SDN controller for redundancy.

In a VMware NSX environment, one cluster of NSX controllers typically includes three or five controllers. To implement the OVSDB management protocol on a Juniper Networks device, you must explicitly configure a connection to one NSX controller, using the Junos OS CLI. If the NSX controller to which you explicitly configure a connection is in a cluster, the controller pushes information about other controllers in the same cluster to the device, and the device establishes connections with the other controllers. However, you can also explicitly configure connections with the other controllers in the cluster, using the Junos OS CLI.

To implement the OVSDB management protocol on a Juniper Networks device in a Contrail environment, you must configure a connection to a Contrail controller, using the Junos OS CLI.

Connections to all SDN controllers are made on the management interface of the Juniper Networks device.


ip-address—IPv4 address of the SDN controller.
