<DIV>Hi Mr. Haoda,</DIV> <DIV> </DIV> <DIV>If i send relay reply message to a multicast address, he is comparing it with an unicast address...</DIV> <DIV> </DIV> <DIV>HDR_IPV6_relay_reply_nut_relay.DestinationAddress received:ff02::1:2 = fe80::200:ff:fe00:a4a4</DIV> <DIV> </DIV> <DIV>But if i send the relay reply to the unicast address fe80::200:ff:fe00:a4a4, the packet is not being received. The IP address is not reflected i feel so because Neighbour Solicitation is being sent to this address and it does not recieve any NA back(This happens only when the interface does not have such an IP address).</DIV> <DIV> </DIV> <DIV>Please comment on this...</DIV> <DIV> </DIV> <DIV>Regards,</DIV> <DIV>Amit</DIV> <DIV> </DIV> <DIV><BR><BR><B><I>haoda <haoda@64translator.com></I></B> wrote:</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">Hi Mr. Amit,<BR><BR>I think the content of the
