EAP110v3 Outdoor: mdns / multicast crosses VLANs
EAP110v3 has different SSIDs and one tagged vlan. Tagged VLAN SSID is not routed to main network. However when doing an mdns request via
`dig -p 5353 @224.0.0.251 example.local` from main wired network and listening in SSID which is connected to VLAN you will see the mdns request.
That should never happen. Using a device flashed OpenWRT with OpenWRT there is no such thing. Also when being connected via ethernet cable to VLAN, the mdns request won't show up there. That's how it should be.
TP-Link was informed by that bug, but no development over more than 3 months now.

I really can't recommend this product. It seems that problem is all software made, but TP-Link didn't manage so far to solve. I'm now switchting to WR802n devices. They are even more energy efficient and run with OpenWRT up to 4 SSIDs.
