--- features: - Enable creation of VXLANs with different multicast addresses in linuxbridge agent allocated by VNI-address mappings. A new config option ``multicast_ranges`` was introduced. other: - Example configuration of ``multicast_ranges`` in ml2_conf.ini under the ``[vxlan]`` config. section ``multicast_ranges = 224.0.0.10:10:90,225.0.0.15:100:900``. For VNI between 10 and 90, the multicast address 224.0.0.0.10 will be used, and for 100 through 900 225.0.0.15 will be used. Other VNI values will get standard ``vxlan_group`` address.
