(usagi-users 03296) Can't ping6 a global address, while link address is OK??

Dear all,

I am building a USAGI network for research purpose.  I
am not using autoconfiguration, but am rather
hard-coding the IPv6 addresses to the hosts.  I then
found some strange behavior in the network when I
tried to ping6 around.

I have 2 machines A and B, which are connected through
a hub.  I could ping6 from A to B with both global and
link addresses, but could only ping6 from B to A with
link address.  Pinging with the global address from B
to A results "Destination Unreachable" error.

The global address for A is hardcoded as
3ffe:302:11:1:250:fcff:fe2a:b616

and for B is hardcoded as 

3ffe:302:11:4:202:44ff:fe90:91af

Why would this happen?  Any idea?

Thanks very much in advance.

Regards,

Patrick
