Hi Peter, nevermind! I see the issue. I’m setting up a hot-standby config with this server and I thought I needed a client tag for the primary server, but I realize that’s incorrect. It’s finding the address now…
The log error message doesn’t really point clearly in the right direction, but I shouldn’t have had that bad config in there either.
Thanks!
Mary Bull

Hi Peter,
Yes, it selects the correct subnet starting with subnet id.

Hi Mary,
?? Is the correct subnet being selected (150136)?
Please share the complete Kea logging for this client.
Kind Regard Peter

Hi Branimir,

In that case, have a look at:

which allows you to give a directive to Kea that a relay agent should
be served by a certain subnet. This can also be done at the
shared-network level if you are using that concept.
Thank you,
