V6 on the TG589 v3

[#1]

It says it needs a destination interface, not address.
Try ping proto=ip addr=fe80::90:1a00:ca3:8d26 intf=Internet instead.
(The problem here is that link-local addresses are only valid on individual interfaces and so the router needs to know which one we want to send it out of)
It might be useful to see the output of dhcp clientv6 iflist to see if a global prefix is successfully being received.

Ok a bit better:

Blank output for dhcp clientv6 iflist? What does ip iplist give?
(Apologies for the scattergun apprach to solving this but I'm still getting to grips with exactly how the Thomson's function, and not just with IPv6!)

For some reason you aren't getting a global addresses - this should be being obtained via DHCPv6. Unfortunately I'm not home at the moment to be able to dig through the config to see why this might be the case....
Prior to you enabling native IPv6 on the interface did you have any other IPv6 config in place (e.g. a 6in4 tunnel) that may have disabled DHCPv6 or otherwise got in the way of it?

[#6]

Nope straight ipv4 config. Never had ipv6 (still haven't)
EDIT:
OK changed the dhcpv6 options:
Now have

Still don't have ping.

[#7]

The ping to GUA addresses won't work until you have a GUA address.
What do you mean by 'OK changed the dhcpv6 options'? What commands did you use? (The DHCPv6 still isn't completing - it is still sitting in the initialisation step).

[#8]

I was in the menu playing with the dhcpv6
:dhcp clientv6 ifadd intf=Internet
:dhcp clientv6 ifattach intf=Internet
:dhcp clientv6 ifrenew intf=Internet
I then dropped and reconnected the ppp.

[#9]

When you executed those commands did the response give any hints as to what the default values of those parameters you didn't set were?
It might be worth running dhcp clientv6 iflist expand=enabled to give the full output which might hint at what these are/were.

[#10]

Nope.
I could reboot it to get it back as I haven't saved the settings.

For a router that is supposed to be ipv6 gold standard enabled. It is being a pita to setup.

[#11]

It is interesting to note that the DHCPv6 Options requested line is empty, and most notably that it is not requesting a prefix delegation (and indeed that would cause the symptoms we are seeing.
Try readjusting your DHCP client options to the following (note the iapd=1 is the prefix delegation request):
dhcp clientv6 ifconfig intf=Internet listenra=enabled stateless=disabled rapidcommit=disabled leasetime=7200 irt=86400 iana=1 iapd=1 duidtype=duid-llt leasehist=enabled

[#12]

If that command doesn't suffice on its own, try these two afterwards:
dhcp clientv6 oro add intf=wan_ip option=domain-name-servers required=enabled
dhcp clientv6 oro add intf=wan_ip option=ia-prefix-delegation required=enabled
This will force the addition of DNS and prefix options to the DHCPv6 request.

[#13]

OK got:

With Internet

[#14]

Did the dhcp clientv6 oro add intf=Internet option=ia-prefix-delegation required=enabled option line work? This is the key one to get working.
(Sorry about the wan_ip interface inclusion - I'm getting these commands from a Thomson CLI reference manual but missed out the interface swap  applicable to your setup)
Remember to run the full dhcp clientv6 iflist expand=enabled command in order to get the full request listed.

[#15]

By the way, I am assuming you are running the latest firmware?
