Well, your router is trying, but your ISP isn't replying, so I'd say you don't have IPv6 yet.
I have had ISPs where if you send a bunch of DHCP solicits/discovers too quickly, then they stop replying. So maybe disable DHCPv6 for a few hours, and enable it while watching it on the packet sniffer, incase it sends a weird response.
Also it shouldn't make any difference, but in IPv6/ND change
alltobridge; your router looks like it's advertising itself as a default route to your ISP's router, and that just seems wrong.
