Description of Linux Bridge agent configuration options
Configuration option = Default value Description
[LINUX_BRIDGE]
bridge_mappings = (ListOpt) List of <physical_network>:<physical_bridge>
physical_interface_mappings = (ListOpt) Comma-separated list of <physical_network>:<physical_interface> tuples mapping physical network names to the agent's node-specific physical network interfaces to be used for flat and VLAN networks. All physical networks listed in network_vlan_ranges on the server should have mappings to appropriate interfaces on each agent.
[VXLAN]
enable_vxlan = True (BoolOpt) Enable VXLAN on the agent. Can be enabled when agent is managed by ml2 plugin using linuxbridge mechanism driver
l2_population = False (BoolOpt) Extension to use alongside ml2 plugin's l2population mechanism driver. It enables the plugin to populate VXLAN forwarding table.
local_ip = None (IPOpt) Local IP address of the VXLAN endpoints.
tos = None (IntOpt) TOS for vxlan interface protocol packets.
ttl = None (IntOpt) TTL for vxlan interface protocol packets.
vxlan_group = 224.0.0.1 (StrOpt) Multicast group(s) for vxlan interface. A range of group addresses may be specified by using CIDR notation. Specifying a range allows different VNIs to use different group addresses, reducing or eliminating spurious broadcast traffic to the tunnel endpoints. To reserve a unique group for each possible (24-bit) VNI, use a /8 such as 239.0.0.0/8. This setting must be the same on all the agents.
