          You should not use this method.
          You probably want `BGP.bfd`.
  
          Args:
              peer_ip (str): Peer IPv4 address for BFD setting.
              min_tx (str): BFD transmit interval in milliseconds (300, 500, etc)
              delete (bool): Remove the configuration if ``True``.
  
          Returns:
              XML to be passed to the switch.
  
          Raises:
              None
