Hi, All,

I'm using a six-to-four setup (2002:cf1:d877::1 is my router's
address), and I'm having serious connectivity problems. I can ping my
default router (2002:4371:c5a::1) and the following addresses:

        www.6tap.net
        gate.ipv6.euronet.be
        ipv6-lab-gw.cisco.com
        3ffe:8100:200:1fff::1
        www.stben.be

but

        ftp8.freebsd.org
        ftp2.jp.freebsd.org
        ftp7.jp.freebsd.org, (sense a pattern? (-: )
        www.kame.net
        3ffe:700:20:4:200:f8ff:fe75:6bc8

all(?) seem to come back with a "No Route to Destination" error; for example:

        PING6(56=40+8+8 bytes) 2002:cf1:d877::1 --> 3ffe:80c0:200:2:250:b7ff:fe14:4156
        64 bytes from 2002:4371:c5a::1: No Route to Destination
        Vr TC  Flow Plen Nxt Hlim
         6 00 00000 0010  3a   3f
        2002:cf1:d877::1->3ffe:80c0:200:2:250:b7ff:fe14:4156
        ICMP6: type = 128, code = 0

Some of the looking glasses act like there's no way to get to 2002::/16,
so I'm guessing that there's something messed up in the routing to and
from 2002-land. The other thing I've noticed is that all the addresses
that *do* work are in 366e::/16. I have yet to get a response from
anything in 2001::/16.

Most of the looking glasses act like everything is fine (inasmuch as
they'll talk to me -- they seem to be offended by junkbuster...), but
www.v6.mfeed.ad.jp gets nowhere.  Its "show bpg ipv6" is broken, it
can't ping me, and traceroute is taking forever...

Any thoughts? I was planning to use IPv6 to do some Real Work, but I
can't get the connectivity I need.

Thanks,
Bill
