      - The name of the route domain.

    description:
      - The bandwidth controller for the route domain.
  connection_limit:
    description:
      - The maximum number of concurrent connections allowed for the
        route domain. Setting this to C(0) turns off connection limits.

    description:
      - Specifies descriptive text that identifies the route domain.
  flow_eviction_policy:
    description:
      - The eviction policy to use with this route domain. Apply an eviction
        policy to provide customized responses to flow overflows and slow
        flows on the route domain.
  id:
    description:
      - The unique identifying integer representing the route domain.
      - This field is required when creating a new route domain.
      - In version 2.5, this value is no longer used to reference a route domain when
        making modifications to it (for instance during update and delete operations).
        Instead, the C(name) parameter is used. In version 2.6, the C(name) value will
        become a required parameter.
  parent:
    description:
      - Specifies the route domain the system searches when it cannot
        find a route in the configured domain.
  partition:
    description:
      - Partition to create the route domain on. Partitions cannot be updated
        once they are created.
