Configuring the networking services

Configure networking on each node. See the basic information about configuring networking in the Networking service section of the Install Guides, depending on your distribution.

OpenStack network nodes contain:

  • Networking DHCP agent

  • Neutron L3 agent

  • Networking L2 agent


The L2 agent cannot be distributed and highly available. Instead, it must be installed on each data forwarding node to control the virtual network driver such as Open vSwitch or Linux Bridge. One L2 agent runs per node and controls its virtual interfaces.
