Hi,
What is wish to do is
There are four interfaces here
PC1---------------------| br0
|if0-------------------if2| br1 | ----------------------PC2
|
|if1------------------- if3| |
br0 and br1- are two transperent bridges on separate devices.
if0 and if1 are two physical interfaces(ports) attached to each of the
bridges on either side.
What i intend to do is to redirect all traffic coming towards br0
from PC1 through interface/port if1, even if the source mac is learnt
through if0 and the same on the other bridge br1 on the other device.
Similarly, any traffic coming from PC2 has to go through if2 instead
of if3 before it enters br0. So in all, what i want to do is make the
link from br0 to br1 full duplex if the physical links are half-duplex.
Regards,
Munro.
