<br>
I would like to make host reservations for multiple MAC addresses that share a single IP(v4) address, for example:<br>
<br>
{<br>
"hw-address": "00:15:e9:7c:56:8e",<br>
"ip-address": "172.16.1.13"<br>
},<br>
{<br>
"hw-address": "00:15:e9:7c:56:8f",<br>
"ip-address": "172.16.1.13"<br>
},<br>
<br>
Unfortunately, this is not possible. I get the following message:<br>
<br>
DHCP4_CONFIG_LOAD_FAIL configuration error using file: /usr/local/etc/kea/kea-dhcp4.conf, reason: failed to add new host using the HW address '00:15:e9:7c:56:8f and DUID '(null)' to the IPv4 subnet id '3' for the address <a href="http://172.16.1.13" rel="noreferrer" target="_blank">172.16.1.13</a>: There's already a reservation for this address<br>
<br>
That was/is possible in the ISC DHCPD.<br></blockquote><div><br></div><div><br></div><div>Do you think that is correct? There shouldn't be / it can't be two the same ip address in the same network, this is ip conflicts and L3 wont work correctly.</div><div><br></div><div>Opposite situation where you share the same mac but with different ip could be considered as correct.</div><div><br></div><div><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">
<br>
Is there a specific reason for that behaviour? And can I change it in any way? Or is my config simply wrong?<br>
<br>
Kind regards,<br>
