Networking Option 2: Self-service networks
Install and 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.conf
file.
In the
[linux_bridge]
section, map the public virtual network to the public physical network interface:[linux_bridge] 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, 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.
In the
[securitygroup]
section, enable security groups, enableipset
, and configure the Linux bridgeiptables
firewall driver:[securitygroup] ... enable_security_group = True enable_ipset = True firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
Return to Networking compute node configuration <neutron-compute-compute>
