Is there some way of the network-side 'distinguishing'
the PPPoE sessions?  maybe they use a different username
i have done that just a couple of hours ago.
You have done a ??that?? -- as in  found out something?
that referring to the previous sentence, have different user
names for the two pppoe sessions
Aaah... see I asked a question, rather than saying "you need
to do x", hence answer was unclear.

also not getting an ipv6 address.

Maybe the fact that one session requests ipv4 and the
  other doesn't, or something...  is all they need...
/usr/sbin/pppd nodetach ipparam wan6 ifname pppoe-wan6 +ipv6 nodefaultroute 
usepeerdns persist maxfail 1 user userid-secret password password-secret 
ip-up-script /lib/netifd/ppp-up ipv6-up-script /lib/netifd/ppp-up 
ip-down-script /lib/netifd/ppp-down ipv6-down-script /lib/netifd/ppp-down mtu 
1492 mru 1492 plugin rp-pppoe.so nic-eth1
/usr/sbin/pppd nodetach ipparam wan ifname pppoe-wan nodefaultroute usepeerdns 
persist maxfail 1 user userid-secret password  ip-up-script /lib/netifd/ppp-up 
ipv6-up-script /lib/netifd/ppp-up ip-down-script /lib/netifd/ppp-down 
ipv6-down-script /lib/netifd/ppp-down mtu 1492 mru 1492 plugin rp-pppoe.so 
nic-eth1


Hrrrm...
I can say that in my static config I am _only_ getting an
fe80:: (link local) IPv6 address on pppoa-wan.  I do NOT get an IPv6
address on the interface.

Seemingly, at least an 10.03.1 you need explicit "ip -6 addr" to
see when an IPv6 address has been assigned.  The default may have
changed now.


However, since I (statically) have IPv6 address on br-lan (internal)
this is sufficient for the router to have a global address that works
for 2-way-communication from the router to internal and from router
to internet-side, no problems.

Some suggest that to get an wan-side IPv6 address you might need
PPP options:-
"+ipv6"
"ipv6cp"
"ipv6cp-use-ipaddr"
But only if the ISP supports IPv6CP.

If your ISP needs DHCPv6 then you basically need that to delegate/
assign a prefix/address to the "br-lan" or equivalent and there is
no need for it to give an interface-level-address on pppoe-wan6,
just an ipv6-default-route.

[on that node, in "ip -6 route" do you have a default ipv6 route,
even if you have no address] ?


Keep thinking.. keep looking.. work out how to debug dhcpv6 and post
details of that too ...  If it can work hopefully it will eventually =).
