><br>
> Hi Francis,<br>
><br>
<br>
Thank you for your response. On the DHCPv6 server side I have added a<br>
static IPv6 to the interface the DHCPv6 server is configured for (i.e.<br>
'enp7s0' has IP 'fd00:0:0:1::3/64' statically assigned to it via 'networkd'<br>
- this interface also gets IP ' fe80::85f4:b665:fd85:3d1e/64' which is used<br>
as link-local address in the router advertisement messages from the DHCPv6<br>
server). In the KEA configuration file I have defined a corresponding<br>
subnet for interface 'enp7s0' as well ' "subnet":<br>
"fd00:0000:0000:0001::/64" '.<br>
Unfortunately I am not sure what you mean with 'Please make the subnet to<br>
serve the interface'? Could you please elaborate a little bit further on<br>
this comment as I thought I am exactly doing that with my current<br>
configuration?<br>
<br>
Thank you so much.<br>
Best,<br>
C<br>
