<p class="MsoNormal">I am hoping someone count point me in the right direction or tell me I’m headed towards a dead-end with setting up overlapping subnets in Kea. I saw in the ARM for the version I am using, 2.6.0, that overlapping subnets are supported however
I am getting an error from kea-dhcp4 daemon that states "...shared-networks: subnet with the prefix of '192.0.2.0/24' already exists", with the configuration I have below.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I've tried with and without placing the subnets under the shared-networks object and several other adjustments, the closest I can get to the desired behavior is to set one subnet up as a /23 and the other as a /24 and adjusting the pools
but this does not meet my requirements. The client-classification and everything works great…. Its just the overlapping subnets that is throwing me for a loop with my configuration.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I did find a post on the Kea user mailing list from 2017, but it was left unanswered.<o:p></o:p></p>
