<div><font size="2" face="Arial"><span class="688005216-25062009">The router/relay
agent is configured to forward the broadcast to both the
servers.</span></font></div>
<div><font size="2" face="Arial"><span class="688005216-25062009">When i send a client
with a mac-address of 00:00:00:00:00:00:01 the router forwards the packet to
both primary and secondry.</span></font></div>
<div><font size="2" face="Arial"><span class="688005216-25062009">On recipt of a
discover the i get a offer from the primary server once and in another instance
the mac address is offered by the secondry .</span></font></div>
<div><font size="2" face="Arial"><span class="688005216-25062009">I am not able to get
how the hashing works. Can any one explain how the hasing
works</span></font></div>

<div><font size="2" face="Arial"><span class="688005216-25062009">Another behaviour
which i would like to mention here . Some times we get offers from both the
servers as the discover is reaching the servers .As per the protocol after
hashing primary or secondry should send an update to the peer and then provide
an offer .The behaviour is contradicting </span></font></div>
