<br>
I am running DHCPv6 on my network to hand out static IPv6 addresses from<br>
a stateless server to a bunch, but not all of my clients.<br>
<br>
Here is my configuration:<br>
<br>
allow leasequery;<br>

", interface-id: ", pick-first-value(v6relay(1, option dhcp6.interface-id),""),<br>
", remote-id: ", pick-first-value(v6relay(1, option dhcp6.remote-id),"")<br>
));<br>

<br>
Since the radvd advertises the networks as managed, all clients send<br>
DHCP requests, and the server logs for each of those requests:<br>
<br>
Nov 21 08:54:59 chasse dhcpd[763]: Solicit message from fe80::5054:ff:fe17:2fe7 port 546, transaction ID 0x811FA800<br>
Nov 21 08:54:59 chasse dhcpd[763]: DHCP6-RELAY client-id: 0:2:0:0:ab:11:f6:cb:ae:dd:18:<wbr>d1:73:c1, interface-id: , remote-id:<br>

Nov 21 08:54:59 chasse dhcpd[763]: Sending Reply to fe80::5054:ff:fe17:2fe7 port 546<br>
<br>
These seriously clutter up my logs, can I tell the server that it should<br>
ignore DHCP solicit messages from clients that it doesn't have static<br>
configuration for? Or is it better to shrug and to have the DHCPv6<br>
server assign a "dynamic" IP address?<br>
<br>
Can I somehow tweak radvd's announcement to keep at least the frequency<br>
of those undesired DHCPv6 solicitations down?<br>
<br>
Greetings<br>
