<p class="MsoNormal"><span style="font-size:11pt">Thank you very much for your reply and correcting this issue.</span><u></u><u></u></p>

<p class="MsoNormal"><span style="font-size:11pt;font-family:"Courier New""> </span><u></u><u></u></p>
<p class="MsoNormal"><span style="font-size:11pt">2) However, I have been following this link:</span><u></u><u></u></p>

<p class="MsoNormal"><span style="font-size:11pt">Which indicated to me that the option “extended-info-tables-enabled” would have provided the same functionality. However, as you pointed out, there was no relay ID in the lease table.</span><u></u><u></u></p>

<p class="MsoNormal"><span style="font-size:11pt">I have since added the global parameter "store-extended-info" as you suggested, and I now see the JSON now at the end of each memfile lease. I hope this helps anyone trying to accomplish the same thing.</span><u></u><u></u></p>

<p class="MsoNormal"><span style="font-size:11pt">Hi Mark,<br>
<br>
Two questions:<br>
<br>
1. Are you using Kea 2.6.1 ? I think the relay-id method was not<br>
available before 2.6<br>
2. Have you globally set "store-extended-info": true ? (see:<br>
</span><a href="https://kea.readthedocs.io/en/kea-2.6.1/arm/dhcp6-srv.html#storing-extended-lease-information)" target="_blank"><span style="font-size:11pt">https://kea.readthedocs.io/en/kea-2.6.1/arm/dhcp6-srv.html#storing-extended-lease-information)</span></a><span style="font-size:11pt"><br>
as this is required as well. It doesn't appear so from the lease you<br>
pasted as I don't see any data in the "user-context" field.<br>
<br>
Thank you,<br>
Darren Ankney<br>
