Summary
This chapter laid the foundation for creating networks and subnets that can be leveraged by routers, instances, and other cloud resources. The Neutron command-line client can be used to manage networks, subnets, and ports and is highly recommended over the limited Horizon dashboard for most administrative tasks.
For more information on network, subnet, and port attributes, as well as for guidance on how to use the Neutron API, refer to the OpenStack wiki at https://wiki.openstack.org/wiki/Neutron/APIv2-specification. In addition, OpenStack operations guides can be found at http://docs.openstack.org/openstack-ops/content/.
In the next chapter, I will expand on the concept of Neutron routers and their involvement in the network, including the configuration and use of floating IPs to provide external connectivity to instances.
