module: nxos_igmp
extends_documentation_fragment: nxos
version_added: "2.2"
short_description: Manages IGMP global configuration.
description:
    - Manages IGMP global configuration configuration settings.
author:
    - Jason Edelman (@jedelman8)
    - Gabriele Gerbino (@GGabriele)
notes:
    - Tested against NXOSv 7.3.(0)D1(1) on VIRL
    - When C(state=default), all supported params will be reset to a
      default state.
    - If restart is set to true with other params set, the restart will happen
      last, i.e. after the configuration takes place.
options:
    flush_routes:
        description:
            - Removes routes when the IGMP process is restarted. By default,
              routes are not flushed.
        type: bool
    enforce_rtr_alert:
        description:
            - Enables or disables the enforce router alert option check for
              IGMPv2 and IGMPv3 packets.
        type: bool
    restart:
        description:
            - Restarts the igmp process (using an exec config command).
        type: bool
    state:
        description:
            - Manages desired state of the resource.
        default: present
        choices: ['present', 'default']
