In the previous chapter, we laid down a virtual switching infrastructure that will support OpenStack Neutron networking features moving forward. In this chapter, we will build network resources on this foundation. I will guide you through the following tasks:
Creating networks and subnets
Attaching instances to networks
Demonstrating DHCP and metadata services
Networks, subnets, and ports—the core resources of the Neutron API—were introduced in Chapter 3, Installing Neutron. The relationship between these core resources and instances, DHCP, and metadata services can be observed in the following sections.
