Bob!
     I am sorry if I did'nt put it correctly, but by saying that the
Loop Detected Notification might in turn Loop, I meant that since a loop
was detected on the label request received, there is a very  high
possibility that the return path (from the receiver of the label request
to the sender of the Label request) for the notification message might as
well loop so its better to silently discard it.

Is'nt it because of this Bob ?

regards
tomar
