I've got the following setup:
A MikroTik router, connected to other two switches on ports ether4 and ether5.
1. I would like to configure Vlans so both ports ether4 and ether5 has carry traffic for all the different vlans in the LAN segment.
2. The Vlan configuration will overlap on both ports, i.e. I'll would like to associate the same vlans on both ether4 and ether5
I realized that I cannot associate a VLAN interface to more than one physical interface. So in order to achieve 2. I'll have to configure bridge interface for each vlan and than associate both ports (ether4 and ether5) for all bridge interfaces associated with any vlan.
This is how I should be able to use a VLAN tag on both interfaces, thorough its respective bridge. But than... what about the isolation? If I have multiple bridges associated with ports ether4 and ether5, will I have an isolation between the VLANs?
Or to put it differently, when I have a bridge interface associated with a VLAN, when the traffic is moved from one physical interface to another, does the Ethernet frame keep its tag?
