<p class="MsoNormal"><span style="font-size:11pt">I configured two client classes for my test RPDs. And I also configured three subnets for three different RPDs. I found that even in the subnet configuration, I have correlated the

“RPD_new”</span> for that subnet 3 to use. But in reality, kea just ignored this configuration, and use the client class “RPD” for all 3 subnets. And because my test RPDs satisfied both “RPD” and “RPD_new” client classes, and my test RPD used the configurations
in “RPD” instead of “RPD_new”. </span></p></div></div></div></blockquote><div><br></div><div>My guess is that the order matters, and it takes the first match.<br></div><div>Your first class matches any client class where the first three characters are "RPD", so it matches both "RPD" and "RPD_new".<br></div><div>You might try putting the RPD_new class first, so it has a chance of matching a client before the RDP class matches.</div><div><br></div><div>-- <br></div><div>Bob Harold<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="msg2834610952364611832"><div lang="EN-US" style="overflow-wrap: break-word;"><div class="m_-490640349275201568WordSection1"><p class="MsoNormal"><span style="font-size:11pt"><u></u><u></u></span></p>
