Hi, 

The following is the result of "traceroute6" from the University of
New Hampshire to WIDE project.

lobster# traceroute6 bravo.v6.wide.ad.jp
traceroute to bravo.v6.wide.ad.jp (5f09:c400:a3dd:ca00::f801:5df5), 30 hops max, 60 byte packets

First, I would like to ask each maintainer to make your router not to
select a link-local source address for a global destination. According
to the 6bone map, fe80::cc7b:2ec is NRL/US(one between UNH/US and
IBM/US).

Second, routing loop occurs. Please check out your routing
tables. 

Thanks.
