Hi,
it looks like you have a route to 3ffe:8271:2101:1::1/128 pointed to your
loopback interface:
> 3ffe:8271:2101:1::1/128 :: U 0 0 0 lo
That's odd and the cause of trouble. Just remove it and the less specific
route to 3ffe:8271:2101:1::/64 thru eth0 will be used in your traceroute.
Regards,
Flavio.
