ip6-localhost (::1) 2990.86 ms !H -> Why ?



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.
