How do you determine that fasttrack is not working fir you? Is it that facttrack counters don’t increment or is it the lack of performance?
Either way, your bridge/vlan setup is a mess making CPU to push the same packet around just too many times. I strongly advise you to redo the whole VLAN config … afrer reading this excelent thread about bridge VLAN filtering.
Ideally packet flow should be something like this:
PC vlanX → ether1 trunk → bridge → vlanX interface → routing engine → vlanY interface → bridge → ether1 trunk → PC vlanY
and that’s same bridge both times.
