If you are running a AVM FritzBox, you can easily enable IPv6 support on this FritzBox (take a look at
this posting). But this is only half the way ;-).
I checked the following clients:
- Ubuntu: autoconfiguration works just out of the box...
- On windows client you have to enable IPv6 support and after that everything works fine...
- Debian: there are no router solicitation (ra) messages sent... ;-(
[and of course no ipv6-connectivity...]
After some checks it was obvious, that the wpa_supplicant-mechanism is the problem. The initialization of wpa needs up to 10s and the ra messages are sent at a time, when the wpa encryption is not set up and the kernel does not resend them.
But there is an easy workaround to resend this messages:
rdisc6 eth1
hades:/etc/network# rdisc6 eth1
Soliciting ff02::2 (ff02::2) on eth1...
Hop limit : 255 ( 0xff)
Stateful address conf. : No
Stateful other conf. : Yes
Router preference : medium
Router lifetime : 1800 (0x00000708) seconds
Reachable time : unspecified (0x00000000)
Retransmit time : unspecified (0x00000000)
Prefix : 2002:5ed5:8422::/64
Valid time : 7200 (0x00001c20) seconds
Pref. time : 3600 (0x00000e10) seconds
Recursive DNS server : fd00::21c:55ff:fe1a:2632
DNS server lifetime : 1200 (0x000004b0) seconds
MTU : 1280 bytes (valid)
Source link-layer address: 00:1C:55:1A:26:32
from fe80::21c:55ff:fe1a:2632
After that ifconfig shows a auto configured ipv6 address:
inet6-Adresse: 2002:5dd2:84d3:0:210:ff:fe0d:1244/64 Gültigkeitsbereich:Global
and the routes are set like they should:
2002:5dd2:84d3:0:210:ff:fe0d:1244/128 :: Un 0 1 351 lo
2002:5dd2:84d3::/64 :: UAe 256 0 4 eth1
::/0 fe80::21c:55ff:fe1a:2632 UGDAe 1024 0 42 eth1
...
