<DL>
<DD>Return a route error in case a route was found to be invalid
 as the current hop cannot find a way to forward the message to the
 destination or any other hops in the forward part of the route.
 In that case a negative route response is forwarded
 to the orginal source of the message. Now of course we
 do not have any way to guarantee that the NACK message will be
 received by the sender, but the best we can do is to try :-)

 we send a query ID to NACKROUTE_QUERYID to indicate
 this is a bad Route
