        *{command}* is used to create interconnect groups. An interconnect group
        connects a set of redundant interconnects between Google and the
        customer.

        For an example, refer to the *EXAMPLES* section below.

        To create an interconnect group capable of PRODUCTION_CRITICAL, run:

          --description="Example interconnect group"

        It is easy to add members to an existing interconnect group after
        creation using the *add-members* command.

        To create an interconnect group capable of PRODUCTION_NON_CRITICAL, with
        two members at creation time, run:

          $ {command} example-interconnect-group
          --intended-topology-capability=PRODUCTION_NON_CRITICAL
