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

Installing and configuring OVS


We have already shown how to set up and configure an ODL node. Let's now proceed to set up an Open vSwitch node. The following steps assume that the Open vSwitch node is running Ubuntu server edition 15.10 or higher.

  1. Install Open vSwitch packages on the Open vSwitch node as follows:

  2. Add an OVS bridge called br-test and add two interfaces as per the topology diagram. Depending on your server, you will have to choose the appropriate network interfaces:

  3. Since these interfaces are bound to an OVS bridge, these should not have any IP addresses assigned to it. Edit the /etc/network/interfaces file and ensure that the following entries are added:

  4. Finally, bring up the two interfaces as follows:

  5. At this stage, the OVS is configured to forward traffic between enp0s8 and enp0s9. If end hosts Host 1 and Host 2 are now connected to these interface, data path traffic will flow via the Open vSwitch (br-test).
