I have no global ipv6 address on the sip0 interface. Here is the result =
I
get:

# ping6 -aag ff02::1%sip0
PING6(72=3D40+8+24 bytes) fe80::200:24ff:fec1:e814%sip0 --> ff02::1%sip0

On ath0:

ping6 -aas ff02::1%ath0
PING6(72=3D40+8+24 bytes) fe80::202:6fff:fe20:f7ec%ath0 --> ff02::1%ath0
^C
--- ff02::1%ath0 ping6 statistics ---
4 packets transmitted, 0 packets received, 100.0% packet loss

I saw the packets arriving on the remote box, but it does not reply... =
Is
there a problem in the packet sent???
