I do not use RPD in v6 mode so I cannot test that but perhaps try to add a line
at the end of the new statement as follows
“always-send”: true
That will force transmission of Option 17 unconditionally if this class is
matched.

Hi Marek,
I have added, but there’s no change. I adjusted the position of this part
configuration to the top and bottom, but still no change.

You need to add
{
"space":
"dhcp6",
"name":
"vendor-opts",
"code": 17,
"data": "4491"
}
to your “option-data” stanza. Otherwise, the process will not insert the
vendor-specific entry in Option 17.

Subject: [Kea-users] No DHCP Reply sent out from kea server
Greetings,
I configured some sub-options for DHCPv6 Option 17 for RPD use. I didn’t find
too detailed information regarding how to customize those sub-options under one
option such as DHCPv6 option 17. Luckily, I found some examples from previous
discussion email. Before I added those options, I could see the Solicit,
Advertise, Request and Reply packets between the RPD and DHCP server. After the
configuration, now I don’t see DHCP server responded to the Advertise packets
anymore. The Advertise packet was sent. I checked the debug logs, I don’t see
any reasons why the Advertise packets are not sent. There’s no errors in the
debug logs.
I define those options globally while use them under the class but they are not
working. Then I changed the configuration and use them under global
configuration, but still no changes. I suspect my customization configuration
for sub-options have some problem. But I don’t see any issue according to
manual 9.2.15. DHCPv6 Vendor-Specific Options. Did I miss something in the
configuration? I also attached my debug settings, not sure if there could be
more detailed debug logs to help our troubleshooting process.
My kea version is 2.4.1.
