Attempting IP6 with auひかり using EdgeRouter

au HIKARI is DUID-LL and should be represented as "00:03:00:01:xx:xx:xx:xx:xx:xx"

So using MAC address aa:bb:cc:dd:ee:ff

My WAN is eth1

configure
set interfaces ethernet eth1 dhcpv6-pd duid "00:03:00:01:aa:bb:cc:dd:ee:ff"
commit
save
exit

But it isn't enough. Using tcpdump I see from the aterm-bl1000hw

09:15:53.430486 IP6 (flowlabel 0x92029, hlim 1, next-header UDP (17)
 payload length: 101) fe80::6ee4:daff:fe43:4831.546 > ff02::1:2.547:
  [udp sum ok] dhcp6 solicit
  (xid=ddacb3 (elapsed-time 65535)
  (option-request SIP-servers-domain SIP-servers-address
  DNS-server DNS-search-list SNTP-servers NTP-server AFTR-Name
  opt_67 opt_82 opt_83 opt_94 opt_95 opt_96)
  (client-ID hwaddr type 1 aabbccddeeff)
  (reconfigure-accept) (Client-FQDN) (IA_PD IAID:1 T1:0 T2:0))

As seen sent by EdgeRouter:

09:14:18.032015 IP6 (hlim 1, next-header UDP (17)
 payload length: 105) fe80::6ee4:daff:fe43:4831.546 > ff02::1:2.547:
   [udp sum ok] dhcp6 solicit
   (xid=1a1e2b
   (client-ID hwaddr type 1 aabbccddeeff)
   (IA_NA IAID:0 T1:0 T2:0) (rapid-commit)
   (elapsed-time 310)
   (option-request DNS-server DNS-search-list)
   (IA_PD IAID:0 T1:0 T2:0
   (IA_PD-prefix ::/48 pltime:4294967295 vltime:4294967295)))

Looking at differences, what stands out are:

IAID: 1 -> 0
IA_PD-prefix: none -> /48
No rapid-commit
option-request: opt_67 opt_82 opt_83 opt_94 opt_95 opt_96

Need to try to get closer to the aterm solicit.

I have no set any firewall rules, nor any internal ip6 work.

Hoping I will see a ip6 added to the nics.
