<br>
</div>This is the config file:<br>
<div class="im"><br>
interface eth1.2 {<br>
AdvSendAdvert on;<br>
AdvManagedFlag on;<br>
AdvLinkMTU 1492;<br>
prefix ::/64 { };<br>
RDNSS fd39::39 { };<br>
DNSSL <a href="http://romanrm.ru" target="_blank">romanrm.ru</a> <a href="http://romanrm.net" target="_blank">romanrm.net</a> <a href="http://romanrm.hk" target="_blank">romanrm.hk</a> <a href="http://version6.ru" target="_blank">version6.ru</a> { };<br>
};<br>
<br>
</div>As you can see /80 is not in it. What you see below in the original message,<br>
is the output of "radvdump" from a LAN client.<br>
