Networking Option 1: Provider networks

Configure the Networking components on a compute node.

Configure the Linux bridge agent

The Linux bridge agent builds layer-2 (bridging and switching) virtual networking infrastructure for instances including VXLAN tunnels for private networks and handles security groups.

  • Edit the /etc/neutron/plugins/ml2/linuxbridge_agent.ini file and complete the following actions:

    • In the [linux_bridge] section, map the public virtual network to the public physical network interface:

      physical_interface_mappings = public:PUBLIC_INTERFACE_NAME

      Replace PUBLIC_INTERFACE_NAME with the name of the underlying physical public network interface.

    • In the [vxlan] section, disable VXLAN overlay networks:

      enable_vxlan = False
    • In the [agent] section, enable ARP spoofing protection:

      prevent_arp_spoofing = True
    • In the [securitygroup] section, enable security groups and configure the Linux bridge iptables firewall driver:

      enable_security_group = True
      firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
