<br>
There is presently no way to replicate the load-balancing hub and<br>
spoke model from ISC DHCP. I do not find any issues here:<br>
<a href="https://gitlab.isc.org/isc-projects/kea/-/issues?sort=created_date&state=opened&label_name%5B%5D=ha" rel="noreferrer" target="_blank">https://gitlab.isc.org/isc-projects/kea/-/issues?sort=created_date&state=opened&label_name%5B%5D=ha</a><br>
related to expanding the functionality of hub and spoke to include the<br>
load balancing mode. Given that both servers in an HA relationship<br>
need to be capable of handling the full client, there isn't much<br>
advantage to load-balancing. Have you considered implementing<br>
hot-standby, when you move to Kea, instead?<br>
<br>
Thank you,<br>

To achieve Active-Active load balancing in Kea, it appears I am limited to 1-to-1 pairs, which would require six server instances (three separate pairs) to achieve the same result. This significantly increases our infrastructure and resource management.<br>
