WAP AC transparent 2 ssid's to 2 vlan's

I’m trying to put an WAP AC to work with the following configuration:
Broadcasting 2 ssid’s that each are connected to a vlan on ether1. This should be all transparent so DHCP should come from the router that is connected on ether1.
I’ve looked at this: http://forum.mikrotik.com/t/advice-configuration-rbwap2nd/103449/7

I can imagine I have to configure 2 bridges but how can I set a default route for each bridge?

Preferably I’d use capman because I have to do several.

Mangle rules to mark the traffic (mark routing), and multiple default routes in the routing tables, based on the route-mark

I won’t help you with Capsman, because I don’t know it very well, but just some info:

Bridge is transparent, you don’t need to set any routes. The only (default) route you need is for the router itself, if you want it to be able to access internet.

For wireless with VLANs, I’d like to direct your attention to vlan-mode parameter of wireless interfaces. For example, this is the essential part of my home AP for guests, where guest VLAN 82 comes as tagged on ether1:

/interface bridge
add name=lan
/interface wireless
set [ find default-name=wlan1 ] ... vlan-id=82 vlan-mode=use-tag ...
/interface bridge port
add bridge=lan interface=wlan1
add bridge=lan interface=ether1

VLAN doesn’t even have to be configured anywhere (not counting vlan-xxx parameters for wireless) if the router doesn’t need to be part of it. Also any IP configuration is only for management purposes, i.e. optional.

But how does the 2nd bridge have its routes?

I’m not sure what are you asking about.

I found the solution:
create 2 bridges
bridge one: add vlan20 and wlan1
bridge two: add vlan30 and wlan2

Now moving on to capsman.

Yes, this is also possible.
