>Description:
I have two PPPoE connections to my ISP, one manages IPv4 (pppoe0), one
manages IPv6(pppoe1), different logins.
The IPv6 one is troublesome.
I do have the PPPoE session running, I can set and run DHCP6c and get my
IPv6 range given to advertise on the internal network.
Doing this I get the IP of the local-link (fe80::*) interface on the ISP
side that answered my DHCP request and I can ping it.
So, I do have PPPoE session, I do have connectivity, problem is that no
IPv6 is given to the pppoe1 interface (except the local-link of course)
and no information is given about the gateway.
setting inet6 autoconf on the interface doesn't change the problem,
using tcpdump I can see the NDP request being sent but no answer.
on the DHCPv6 part I can see this error too
Mar/23/2016 10:36:50: get_ia: make an IA: NA-0
Mar/23/2016 10:36:50: update_ia: status code for NA-0: no addresses
Mar/23/2016 10:36:50: update_ia: IA NA-0 is invalidated
Mar/23/2016 10:36:50: remove_ia: remove an IA: NA-0
from what I could understand, it would seem that the kernel PPP doesn't
correctly get the informations from ipv6cp and
1-doesn't give IPv6 address to the PPPOE interface
2-doesn't advertise the default route
