Reason:

This function is known to have bene broken for long time, and depends on the unmaintained library

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.

<None>

Minimum Value:

0

Maximum Value:

65535

The UDP port used for VXLAN communication. By default, the Linux kernel does not 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 compatibility.

l2_population

boolean

Default:

False

Extension to use alongside ML2 plugin’s l2population mechanism driver. It enables the plugin to populate the 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.
