[Click] Problem with tap device's communication

[sendoa vaz]

Hello everybody,

I am trying to communication two or more ethernet switches and for that I am
running each switch configuration separately using the userlevel module. For
the connection between switches first I used the click-combine tool but the
element RouterLink was unknown for the compiler and I got errors. I decided
then to use tap devices and model every link between the switches using one
tap device per link. I don't get any error but I don't know why the packets
aren't forwarded or broadcasted. These are the configuration examples of
three switches, they are pretty the same...I have created the tap devices
previously using the command tunctl.

Switch1.click

Switch0  :: EtherSwitch();

FromDevice(tap0)->[0]Switch0[0]->q0::Queue->ToDevice(tap0)
TimedSource-> EtherEncap(0x0800, 1:1:1:1:1:1,
2:2:2:2:2:2)->[1]Switch0[1]->Discard

Switch2.click

Switch1  :: EtherSwitch();

FromDevice(tap0)->[0]Switch1[0]->q0::Queue->ToDevice(tap0)
FromDevice(tap1)->[1]Switch1[1]->q0::Queue->ToDevice(tap1)

Switch3.click

Switch2  :: EtherSwitch();

FromDevice(tap1)->[0]Switch2[0]->q0::Queue->ToDevice(tap1)

Does anyone know what am I doing wrong?
Or does anyone have another idea to connect the switches using tap devices??

Thanks in advance
