Athanasius<p>Oh, that's why me KEA dhcpv6 configuration wasn't working:</p><p>1) I'd converted the configuration over from my prior isc-dhcpv6 one.<br>2) The configuration has some fixed address assignments, specified via duid, but these weren't working.<br>3) The dhcpv6 'ADVERTISE' message in this case was saying "Server could not select subnet for this client".</p><p>It turns out that the example configuration makes NO MENTION of needing an `"interface": "..."` stanza within the `"subnet6"` section. This is to tell the server the network is local and that, yes, it can reach such clients.</p><p><a href="https://techhub.social/tags/isc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>isc</span></a> <a href="https://techhub.social/tags/kea" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>kea</span></a> <a href="https://techhub.social/tags/isckea" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>isckea</span></a> <a href="https://techhub.social/tags/dhcpv6" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>dhcpv6</span></a> <a href="https://techhub.social/tags/linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>linux</span></a></p>
