If there is no entry in the cgkZoneSubnetTable matching the subnet of the GRQ originator, then the gatekeeper uses the value of this object for determining the response. The description of the value is: enable Gatekeeper response to a GRQ/LRQ is GCF/LCF if the GRQ/LRQ has a matching or NULL gatekeeperIdentifier. disable Gatekeeper does not respond if the gatekeeper identifier in the GRQ/LRQ doesn't match.
