Configure the Networking components on a compute node.
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 Host 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
Host 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.
