Matthew Kassawara 117606139c Install: Neutron updates for Mitaka 
Update neutron content for Mitaka.

1) Change 'public' to 'provider' and 'private' to
   'self-service' to improve distinction between these
   networks using neutronish terms.
2) Remove explicit installation of some packages due to
   dependency fixes.
3) Remove explicit configuration of verbosity.
4) Remove explicit configuration of ARP spoofing protection.
5) Remove extraneous configuration for the metadata agent.
6) Remove extraneous configuration for nova-neutron
   interaction.
7) Reduce discussion of MTU because Mitaka fixes most
   of the issues, but we still need to explain the
   most limitation of overlay networks.
8) Generally improve wording.

Networking Option 2: Self-service 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 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 provider virtual network to the provider physical network interface:

      [linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME

      Replace PROVIDER_INTERFACE_NAME with the name of the underlying provider physical network interface. See environment-networking for more information.

    • In the [vxlan] section, enable VXLAN overlay networks, configure the IP address of the physical network interface that handles overlay networks, and enable layer-2 population:

      [vxlan]
enable_vxlan = True
local_ip = OVERLAY_INTERFACE_IP_ADDRESS
l2_population = True

      Replace OVERLAY_INTERFACE_IP_ADDRESS with the IP address of the underlying physical network interface that handles overlay networks. The example architecture uses the management interface to tunnel traffic to the other nodes. Therefore, replace OVERLAY_INTERFACE_IP_ADDRESS with the management IP address of the compute node. See environment-networking for more information.

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

      [securitygroup]
...
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

Return to Networking compute node configuration <neutron-compute-compute>.
