Learning OpenStack Networking (Neutron)

By: James Denton

Overview of this book

OpenStack Neutron is an OpenStack component that provides networking as a service for other OpenStack services to architect networks and create virtual machines through its API. This API lets you define network connectivity in order to leverage network capabilities to cloud deployments. Through this practical book, you will build a strong foundational knowledge of Neutron, and will architect and build an OpenStack cloud using advanced networking features. We start with an introduction to OpenStack Neutron and its various components, including virtual switching, routing, FWaaS, VPNaaS, and LBaaS. You’ll also get hands-on by installing OpenStack and Neutron and its components, and use agents and plugins to orchestrate network connectivity and build a virtual switching infrastructure. Moving on, you’ll get to grips with the HA routing capabilities utilizing VRRP and distributed virtual routers in Neutron. You’ll also discover load balancing fundamentals, including the difference between nodes, pools, pool members, and virtual IPs. You’ll discover the purpose of security groups and learn how to apply the security concept to your cloud/tenant/instance. Finally, you' ll configure virtual private networks that will allow you to avoid the use of SNAT and floating IPs when connecting to remote networks.

L3 metering

The L3 metering extension enables administrators to assign labels to networks to facilitate the metering of the traffic traversing a virtual router. A metering label contains metering rules and is associated with a tenant. The following Neutron commands are specific to the L3 metering extension:

  • meter-label-create

  • meter-label-delete

  • meter-label-list

  • meter-label-rule-create

  • meter-label-rule-delete

  • meter-label-rule-list

  • meter-label-rule-show

  • meter-label-show

The Neutron metering agent can be installed on the node hosting the Neutron router with the following command:

# apt-get install neutron-metering-agent

The configuration file can be found at /etc/neutron/metering-agent.ini. The configuration and use of the Neutron metering agent is outside the scope of this book. For more information on the metering agent, refer to the blueprint at the following location:
