Hi Manav,
        Sorry for the late reply...

        According to u what I understand is that the
forwarding address is always to a router if it is
Nonzero value.
        But I didn't understand how to reach another AS with
this Forwarding address.
        Can u make the concept clear that the forwarding
address will always be to a router when it is a non
zero value.
regards,
alex
