How to properly setup IPV6 over PPPoE?

[null31]

The more experienced / knowledgeable can correct me here, but why are you using “DHCP Client” & “PPPoE”, usually you will use one or the other?

Is common to use DHCPv6-client on pppoe-client interface to get the IPv6 prefix.
In Brazil is common this form on ADSL, VDSL and FTTH.
Only cable (docsis, utp) uses DHCPv4/v6-client to get the address.

Under IPv6 → ND you can set the prefered lifetime und the valid lifetime for every prefix or globally. Maybe this will help
