+module: fortios_router_multicast6
+short_description: Configure IPv6 multicast in Fortinet's FortiOS and FortiGate.
+description:
+    - This module is able to configure a FortiGate or FortiOS by allowing the
+      user to set and modify router feature and multicast6 category.
+      Examples include all parameters and values need to be adjusted to datasources before usage.
+      Tested with FOS v6.0.2
+version_added: "2.8"
