Hi, all,
Just found the problem and would like to share with you all:
After I disabled the "ip forward-protocol spanning-tree" the broadcast now
can be translated to multicast, I can see mroute packets and local
broadcast.
Thx,

Hi ,
Please try to change your group number as its not a multicast address . its
in class C address range . on the other end you have to reconvert your
multicast to broadcast again assuming you have same kind of clients other
end .also please Remove no ip mroute-cache .
i hope it will help
Haroon
