Summary
This chapter covered some important topics related to OpenContrail. We started off with a DevStack-based installation of OpenStack to show the integration between OpenStack and OpenContrail. We covered basic virtual network-related concepts in OpenContrail and then jumped into the flow of packets in an OpenContrail-based software-defined network. We closed the chapter with the crucial service chaining capability, which allows virtual networks to be connected to NFV entities to provide rich networking capabilities using OpenContrail. There are several more important concepts related to OpenContrail, such as more complex traffic flows, analytics, multi-level service chaining, and scalability/redundancy support. Covering all these topics will make this book unwieldy, so we recommend the reader uses this chapter as the basis for an independent study of OpenContrail.
