Chapter 1, Introduction to OpenStack Networking, introduces OpenStack Networking along with supported networking technologies and examples of how to architect the physical network to support an OpenStack cloud.
Chapter 2, Installing OpenStack, provides instructions to install the core components of the Pike release of OpenStack on the Ubuntu 16.04 LTS operating system, including Keystone, Glance, Nova, and Horizon.
Chapter 3, Installing Neutron, explains how to install the Neutron networking components of OpenStack. We will also cover the internal architecture of Neutron, including the use of agents and plugins to orchestrate network connectivity.
Chapter 4, Virtual Network Infrastructure Using Linux Bridges, helps you to install and configure the ML2 plugin to support the Linux bridge mechanism driver and agent, and demonstrates how Linux bridges can be used to connect instances to the network.
Chapter 5, Building a Virtual Switching Infrastructure Using Open vSwitch, helps you to install and configure the ML2 plugin to support the Open vSwitch mechanism driver and agent, and demonstrates how Open vSwitch can be used to connect instances to the network.
Chapter 6, Building Networks with Neutron, walks you through creating networks, subnets, subnet pools, and ports.
Chapter 7, Attaching Instances to Networks, demonstrates attaching instances to networks and explores the process of obtaining DHCP leases and metadata.
Chapter 8, Managing Security Groups, examines the use of iptables to secure instance traffic at the compute node and walks you through creating and managing security groups and associated rules.
Chapter 9, Role-Based Access Control, explains how access control policies can limit the use of certain network resources to groups of projects.
Chapter 10, Creating Standalone Routers with Neutron, walks you through creating standalone virtual routers and attaching them to networks, applying floating IPs to instances, and following the flow of traffic through a router to an instance.
Chapter 11, Router Redundancy Using VRRP, explores the Virtual Routing Redundancy Protocol and its use in providing highly-available virtual routers.
Chapter 12, Distributed Virtual Routers, walks you through creating and managing virtual routers that are distributed across computes nodes for better scale.
Chapter 13, Load Balancing Traffic to Instances, explores the fundamental components of a load balancer in Neutron, including listeners, pools, pool members, and monitors, and walks you through creating and integrating a virtual load balancer into the network.
Chapter 14, Advanced Networking Topics, looks at other advanced networking features, including VLAN-aware VM functionality that allows virtual machine instances to apply 802.1q VLAN tags to traffic, BGP Speaker functionality that provides dynamic routing to project routers, and network availability zone functionality that can be used to separate critical networking components such as DHCP and L3 agents into zones.
