Hello,
thank you for using Kea! I have to point out that we didn't change
license on flex id hook. Hook included into your config file is flex
option hook which is completely different thing from flex id. And flex
option is released in standard package.

I believe ISC has released the flex hook for KEA 2.0 in the standard package.
At least the flex library is part of the installation under
/usr/lib64/kea/hooks/
And defining the library seems to give no error messages.
"library": "/usr/lib64/kea/hooks/libdhcp_flex_option.so",
"parameters": {
"identifier-expression": "relay4[2].hex"
}
Do I need to define circuit-id here under parameters?
My challenge is also how to use circuit-id identifier correctly in a test under
client-classes.

Subject: Re: [Kea-users] Selecting subnet based on circuit-id (OPEN)
The flexible identifier hook for kea will allow you to use the dhcp option 82
sub option 1 as an identifier for leases. The flex hook is part of the premium
hook packages though, purchasable on Isc’s website. The package also comes with
the legal logging hook.
My setup has the same concept, for my VLANs I set them up as individual
interfaces on my box, then I define those interfaces for each subnet in the
configuration. I use the flex it to use the circuit id as an identifier with
“replace-client-id”: true
Even though the circuit id does have the VLAN in it, I choose subnets by the
interface the packet comes in on instead.

Hi
I've just set up KEA 2.0 on a RHEL 8 box using RedHat Repository setup as
instructed at cloudsmith.io.
Seems that the packages available for me now is kea.x86_64, kea-devel.x86_64,
kea-hooks.x86_64 and kea-libs.x86_64 all of which I have installed.
Seems though I'm missing some libraries mentioned in the kea-dhcp4.conf file
like libdhcp_legal_log.so and control-agent-commands.so but I assume they're
not critical.
What I initially need is to be able to select beween subnets based on which
VLAN/VPN the request comes from. My network guys has set up several Cisco
routers which will assign clients to one specific VLAN/VPN if the client
manages to authenticate using 802.1x and to another if the authentication
fails. Am I correct to believe that Cisco router will supply me with
information on which VLAN/VPN a client was assigned to using circuit-id? Is
this a parameter already predefined in KEA or do I have to define it somewhere?
Thanks,
./PerW
