<p class="MsoNormal">Hi All<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have been using dhcpd for IPv4 centralised management of pools in the lab and now have to do the same for IPv6<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I believe I have dhcp6s configured to run ok but I’m obviously doing something wrong
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Scenario is I have remote LAN’s attached to Cisco routers configured with ipv6 dhcp relay to the remote dhcp6s device and I can see the icoming requests but it doens’ match the pool and assign addresses for a start and I have unsupported
options <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So I think the issue is my config is bad for remote LAN’s so I’m not matching a pool properly in the config but I can’t find an example online to follow.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The dhcpc client is attached to the router which has an interface address of 2010:123::1/64 and relays towards the DHCPv6 server from the 2010:3::1 address<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
