Subject: Re: Kea DHCP6 issue!
Hi,
Thank you for replying me back.
Actually the second message you were seeing was from the Cisco ASR where Managed config flag is set to 1.
I have disabled Ipv6 pool on router and now there is no reply back from router. Please have a look at the attached capture file.
The problem which I am facing is the IPv6 clients are getting IP's from the server but not from the pool which I defined in the configuration.
[cid:eb4f0b68-eb57-49a2-9669-1719ffcd400e]
[cid:77ed4fbb-ae6e-47eb-b3f1-13821f57a7a4]
I have already reserved addresses for both DUID and physical address which can be seen in the above log, the client was suppose to get 2022:1200:1100:1000::170/64 address but it is automatically assign some random IAA address.
Here is the kea dhcp6 configuration:

}

}
]
}],

"output_options": [
{
"output": "/var/log/kea-dhcp6.log"
}
],

}
]
}
}
Please have a look and kindly let me know what I am doing wrong.
Waiting for your earliest reply.
Thank you!
Kind regards,
Khalid

Hi,
You've sent this mail to kea-users-owner, an administrative address that
can possibly help with subscribing and unsubscribing to the list.
Please resend to kea-users at lists.isc.org.
Cheers,
Tomek
p.s.
I took a quick look.
First, you provided a lot of information, but didn't say what exactly is
the problem you are trying to solve. If you expect anyone debug your
network for you, you need to provide some pointers.
Second, the traffic capture you provided has two REPLY messages for most
client messages. These are sent by two different DHCPv6 servers. From
your diagram it seems you have only one server running, but you actually
have two.
Third, you mentioned a problem with address release. I don't see any
RELEASE messages in the capture.
