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
```
