[RP-PPPoE] rp-pppoe-server + IPv6

[Blackhold]

Hi,
Once PPPoE server is working taking values from an external radius I'm
trying to get work IPv6 on client.

This is the config of radius for my client

mysql> select * from radreply where username='laura.mora';
+----+------------+-----------------------+----+--------------------------+
| id | username   | attribute             | op | value                    |
+----+------------+-----------------------+----+--------------------------+
| 67 | laura.mora | Framed-IPv6-Prefix    | := | 2a00:1508:6001:dead::/64 |
| 66 | laura.mora | Framed-Route          | := | 0.0.0.0/0 192.168.69.1 1 |
| 60 | laura.mora | Framed-IP-Address     | := | 5.10.205.189             |
| 62 | laura.mora | Port-Limit            | := | 1                        |
| 63 | laura.mora | Service-Type          | := | Framed-User              |
| 64 | laura.mora | Acct-Interim-Interval | := | 60                       |
| 65 | laura.mora | Framed-Compression    | := | Van-Jacobsen-TCP-IP      |
+----+------------+-----------------------+----+--------------------------+

Then I added IPv6 to dictionary on radiusclient

#
#       RFC3162 IPv6 attributes
#
ATTRIBUTE       NAS-IPv6-Address        95      string
ATTRIBUTE       Framed-Interface-Id     96      string
ATTRIBUTE       Framed-IPv6-Prefix      97      string
ATTRIBUTE       Login-IPv6-Host         98      string
ATTRIBUTE       Framed-IPv6-Route       99      string
ATTRIBUTE       Framed-IPv6-Pool        100     string

I was not able to locate wich is the value of the 85 id.

In logs I found that:

The line that I'm mentioning is:
Unsupported protocol 'IPv6 Control Protocol' (0x8057) received

and
rc_avpair_gen: received unknown attribute 85 of length 4: 0x0000003C

also I found various lines that I don't really know what means:
rc_own_ipaddress: couldn't get own IP address
sent [LCP EchoReq id=0x1 magic=0x194ec2f4]
rcvd [LCP EchoRep id=0x1 magic=0xeb70d5]


IPv4 is working and client is getting correct IPv4.

On the PPPoE server I have an IPv6 and the global IPv6 prefix from the
router is forwarded to PPPoE server global IP.
Server is able to ping to internet using his global IP.

Thanks you much!
