short_description: Configure multicast addresses in Fortinet's FortiOS and FortiGate.
description:
    - This module is able to configure a FortiGate or FortiOS by
      allowing the user to configure firewall feature and multicast_address category.
      Examples includes all options and need to be adjusted to datasources before usage.
      Tested with FOS v6.0.2
version_added: "2.8"
