For the past 2 years, I've been struggling to get FastTrack working in my config. Problem is that FastTrack is not working when you have a router-on-a-stick configuration with each VLAN in a different bridge.
I don't know why is that, but it is really annoying especially when you want to send big files between VLANs.
I will give you an example. Let's say I want to send a file from VLAN 211 to 212 and traffic goes like this:
[PC from VLAN 211] -> Ether1 -> Bridge0 -> vlan2 (211) -> Bridge2 -> Router -> Bridge3 -> vlan3 (212) -> Bridge0 -> Ether1 -> [PC from VLAN 212]
Then FastTrack is not working at all.
But when I remove 1 bridge on the route, and move IP and DHCP server on VLAN interface, then FastTrack is working as it should.
[PC from VLAN 211] -> Ether1 -> Bridge0 -> vlan2 (211) -> Bridge2 -> Router -> vlan3 (212) -> Bridge0 -> Ether1 -> [PC from VLAN 212]
Can somebody explain to me, why it's working like this? Or maybe it's a bug? Is it possible to fix this?
