<br>
When you say "still see the router entry being sent" are you just checking<br>
the resulting IP configuration on the client, or are you actually capturing<br>
the DHCP response with Wireshark or similar?<br>
<br>
If you haven't captured the actual response on the wire, that'd be my next<br>
step to see if it's the client that's somehow remembering the information.<br>
