I see MFEA "Interface started" message for eth0, but I don't see
such message for eth1:

-> sorry i didnt configured eth1 for mfea. now i configured it.
still its not forwarding . the scenario is like this. and i am attaching
config.boot
         eth0                            eth1
eth0                     eth0

192.168.1.xx
192.168.1.xx

i am running multicast streamer in 192.168.5.xx to group 225.0.1.45 and want
to  access the stream in 192.168.1.xx

show interfaces output is.

Also, what is the output of the "ip addr" UNIX command, and can you
double-check that the eth1 cable is connected properly.
Finally, what is the output of the "show interfaces" and
"show mfea interface" xorpsh commands.
