Overview of this book

OpenStack Networking is a pluggable, scalable, and API-driven system to manage physical and virtual networking resources in an OpenStack-based cloud. Like other core OpenStack components, OpenStack Networking can be used by administrators and users to increase the value and maximize the use of existing datacenter resources. This third edition of Learning OpenStack Networking walks you through the installation of OpenStack and provides you with a foundation that can be used to build a scalable and production-ready OpenStack cloud. In the initial chapters, you will review the physical network requirements and architectures necessary for an OpenStack environment that provide core cloud functionality. Then, you’ll move through the installation of the new release of OpenStack using packages from the Ubuntu repository. An overview of Neutron networking foundational concepts, including networks, subnets, and ports will segue into advanced topics such as security groups, distributed virtual routers, virtual load balancers, and VLAN tagging within instances. By the end of this book, you will have built a network infrastructure for your cloud using OpenStack Neutron.

Building Networks with Neutron

In the Chapter 4, Virtual Network Infrastructure Using Linux Bridges, and Chapter 5, Building a Virtual Switching Infrastructure Using Open vSwitch , we laid down a virtual switching infrastructure that would support the OpenStack Neutron networking features that we have discussed in this book. In this chapter, we will build network resources on top of that foundation. These will be able to be consumed by instances.

In this chapter, I will guide you through the following tasks:

  • Managing networks using the CLI and dashboard
  • Managing IPv4 subnets using the CLI and dashboard
  • Managing subnet pools
  • Creating ports

Networks, subnets, and ports are the core resources of the Neutron API, which was introduced in Chapter 3, Installing Neutron. The relationship between these core resources and instances and other virtual network devices can be observed in...
