<p class="MsoNormal"><span lang="HR" style="font-size:11.0pt;mso-fareast-language:EN-US">Yes, the traffic is relayed. I was actually thinking of a case where the relay IP address is the same on traffic received on both interfaces. For example, if you have different
VRFs on different interfaces. On the underlaying Linux of the KEA server, the VRFs don't need to be configured at all, but I might want to handle the DHCP server for multiple VRFs from the same server. In this case, it would make sense to force certain subnets
to listen only on specific interfaces.<o:p></o:p></span></p>

<br>
Is the traffic being relayed? I can't think why subnets would be<br>
available on multiple interfaces unless the interfaces are bonded for<br>
local broadcast traffic.<br>
