####################

*Internet Group Management Protocol (IGMP) support*

Type: ``bool``

Help
====

.. code-block:: none

    The value depends on your network needs. IGMP should normally be
    enabled if IPv4 multicast support is needed. Currently we support
    IGMPv2 and earlier versions. This requires IPv4 header support
    because IP Router Alert option must be sent.
    See RFC 2236 for details.
