Thanks Sir,<div><br><div>Thats what I expected. Do you think this will change if I use only two values with huge difference in each other, lets say {26000,29000} ?</div><div><br></div><div>Regards,</div><div>Sammy<br><br><div class="gmail_quote">

Hi,<br>
<br>
this functionality uses a generic "hash" function to generate an<br>
Integer-Value of the PVAR and then reduces this to the number hosts in<br>
your destination set.<br>
If you have only using two different values of the PVAR and only two<br>
hosts in the dispatcher list, it can likely happen, that the same host<br>
is choosen. You should try a wider range of values for your PVAR...<br>
(e.g. try 1000 different values), then you should see a distribution.<br>
