224.0.0.1

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.

local_ip

IP address of local overlay (tunnel) network endpoint. Use either an IPv4 or IPv6 address that resides on one of the host network interfaces. The IP version of this value must match the value of the ‘overlay_ip_version’ option in the ML2 plug-in configuration file on the neutron server node(s).

udp_dstport
Type

port number

Default

<None>

Minimum Value

0

Maximum Value

65535

The UDP port used for VXLAN communication. By default, the Linux kernel doesn’t use the IANA assigned standard value, so if you want to use it, this option must be set to 4789. It is not set by default because of backward compatibiltiy.

l2_population
Type

boolean

Default

False

Extension to use alongside ml2 plugin’s l2population mechanism driver. It enables the plugin to populate VXLAN forwarding table.

arp_responder
Type

boolean

multicast_ranges
Type

list

Default

[]

Optional comma-separated list of <multicast address>:<vni_min>:<vni_max> triples describing how to assign a multicast address to VXLAN according to its VNI ID.
