Hello!

I'm trying to set up an Ipv6, my provider has dual stack and is using prefix delegation /64.
I tried different radvd configurations from wiki and posts on this forum. Nothing seems to work for me - I only see scope-link addresses.

I don't have a modem, it's a FTTH type connection.
Customer support says "It's supposed to be automatic" and I couldn't get anything else out of them.

I could use any help - I'm stuck and don't know what else to try. Would appreciate any working radvd configurations.

Do you get a public ipv4 address on the WAN?

1) If you get a /64 Global address on the WAN, there is a upstream router that have already taken the /64 PD.

2) With a PD, you will get a Global address on br0

Yes, sure I do get Ipv4.

Supposedly, I should also get Ipv6, but I don't see anything really on my br0/eth0:

Code:
br0       Link encap:Ethernet  HWaddr XX:XX:XX:XX:XX:XX
          inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::6238:e0ff:febd:aec1/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:32294752 errors:0 dropped:0 overruns:0 frame:0
          TX packets:22917407 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:18894077606 (17.5 GiB)  TX bytes:33260141578 (30.9 GiB)



All the other interfaces look the same, no scope:global anywhere. Same on stock firmware. But my ISP says that I should be getting it...

Yes, but is it a public address i.e not 10.x.x.x, 172.16-32.x.x or 192.168.x.x?

Try this in dhcp6c custom:

interface eth0 {
send rapid-commit;
send ia-pd 1;
request domain-name-servers, domain-name;
};

id-assoc pd 1 {
prefix ::/64 infinity;
prefix-interface br0 {
sla-id 0;
sla-len 0;
};
};


Check that eth0 is correct for your WAN interface

Tried, no luck. After days of struggle I'm starting to believe something could be misconfigured on the provider's side, it shouldn't be that difficult to set it up ):
