<div dir="ltr"><p dir="auto">For greater visibility, I'm posting here, as I have also submitted a gitlab issue here:<br><a href="https://gitlab.isc.org/isc-projects/kea/issues/1047">https://gitlab.isc.org/isc-projects/kea/issues/1047</a><br><br>The tl;dr is Kea DHCP4 is not sending subnet options to clients and we don't know why.<br><br>We have paid for the premier hooks, so were running kea with the mysql configuration backend for hosts, subnets and leases. This is a dhcp4 only environment.</p>
<p dir="auto">Our environment consists of around 300 subnets</p>
<p dir="auto">We have a test host with a out of band management device that is set to use our new kea server via dhcp helper address.</p>
<p dir="auto">If we update kea, via posting a subnet config to the agent controller, for this management network, we can restart the out-of-band management device and it gets an address and a gateway</p>
<p dir="auto">If we add a few more subnets, again, posting a subnet config to the agent controller, we can restart the OOB device and it gets an IP address and a gateway</p>
<p dir="auto">This is where things get weird.</p>
<p dir="auto">If we add all 300+ subnets, and restart the OOB device, it does not get a gateway. It gets a leased ip address, but no subnet options.</p>
<p dir="auto">Our packet captures during these events shows our OOB device requesting a gateway, but kea never sends one or any of the other options<br></p></div>
