Topic: DHCPv6 PD (Prefix Delegation) failing with NotOnLink status code

The content of this topic has been archived on 20 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hello!

I'm trying to use DHCPv6 with PD (prefix delegation) on my TPLink WDR-4300 (Chaos Calmer 15.05.1) connected to my ISP (NET Virtua in Brazil) cable modem (bridge mode) but the last packet (Solicit->Advertise->Request->Reply) is being received with status code NotOnLink. Am I doing something wrong or maybe is my ISP that is doing wrong? Here is the transaction:

Is is possible to see the wan6 stanza of your /etc/config/network?

It looks like the ISP is at fault, but it would be good to see your config.

Sure, here it is:

config interface 'wan'
        option ifname 'eth0.2'
        option proto 'dhcp'

config interface 'wan6'
        option ifname '@wan'
        option _orig_ifname '@wan'
        option _orig_bridge 'false'
        option proto 'dhcpv6'
        option reqaddress 'try'
        option reqprefix 'auto'

That looks just like mine (which works). I think it is a problem on the ISP's end. I would suggest you open a support ticket with them.

Just to put an end to this thread, I upgraded my router to LEDE 17.01.4 and now everything is working fine.

Thank you cvmiller for the attempt to help!

Glad you got it working.

The discussion might have continued from here.
