It depends on what else you want from the device providing this functionality. Any Mikrotik device with at least three Ethernet interfaces can do this using a software bridge, but it may become a bottleneck - you haven't stated the actual bandwidth of the two "circuits". If you want that to be done on wire speed, you need a device with a switch chip supporting VLAN processing, i.e. at least hAP ac2. And then another question is whether you need multiple isolated bridges - only some CRS devices support multiple bridges with hardware forwarding using a switch chip. On most devices, the switch chips are simpler and only one of the bridges can be fully integrated with the switch chip, the rest are pure software ones. On the other hand, the CPU of some models is so powerful that they can bridge 2 Gbit/s in software, but that would probably not be an efficient solution for your case.
So again, without knowing the complete concept, it is hard to give a better advice.
