If you haven't figured out already that means that your ISP router is = not answering to all routers multicast address which could mean that the = other end has not been configured as a router or that there is no IPv6 = on the other side (I would guess that it is the latter)? Ask your ISP to = check their configs and run e.g. tcpdump? If you ping the default = gateway with tcpdump you should at least see neighbour solicitation = going out and neighbour advertisement coming in with the default gateway = address to your machine if the ISP:s interface has the address.
