Overview of this book

Networking is one the pillars of OpenStack and OpenStack Networking are designed to support programmability and Software-Defined Networks. OpenStack Networking has been evolving from simple APIs and functionality in Quantum to more complex capabilities in Neutron. Armed with the basic knowledge, this book will help the readers to explore popular SDN technologies, namely, OpenDaylight (ODL), OpenContrail, Open Network Operating System (ONOS) and Open Virtual Network (OVN). The first couple of chapters will provide an overview of OpenStack Networking and SDN in general. Thereafter a set of chapters are devoted to OpenDaylight (ODL), OpenContrail and their integration with OpenStack Networking. The book then introduces you to Open Network Operating System (ONOS) which is fast becoming a carrier grade SDN platform. We will conclude the book with overview of upcoming SDN projects within OpenStack namely OVN and Dragonflow. By the end of the book, the readers will be familiar with SDN technologies and know how they can be leveraged in an OpenStack based cloud.

Preface

Managing OVS Using OpenDaylight


Next, we will show you how to manage the OVS instance called br-test using an ODL controller. This will complete the whole setup and configuration:

  1. On the Open vSwitch node, set the ODL controller IP address on the OVS bridge instance. as shown in the following screenshot. In your setup, the IP address of the ODL controller may be different. By default, ODL listens to port 6633 for OpenFlow protocol messages.

  2. Once the preceding command is successfully executed, the OVS instance br-test will send OpenFlow messages to the ODL controller. We can now log in to our ODL DLUX GUI and view details about the OVS and the hosts.

  3. Open a browser and navigate to http://<controller-ip-address>:8181/index.html#/topology. This will display OVS and the host topology, as shown in the following screenshot:

  4. In the left navigation bar, click on the Nodes. This will show a tabular view of the OVS instance. The number 3 indicates the number of ports on OVS instance:
