I have bought a MikroTik hAP ac². I want to use the device to connect via WiFi to bridge to wired clients connected directly to the Mikrotik. I would like the Mikrotik to connect via 5GHz WiFi and if this is down use 2.4GHz. The same SSID is used for both 2GHz and 5GHz. I do not use vlans. My plan was to enable RTSP and prioritize the 5GHz link so, if it failed, RTSP would allow forwarding on the 2GHz interface. If I enable both 2GHz and 5GHz wifi networks I end up with a ethernet loop. I can see both wifi interfaces are in forwarding mode if both are enabled. I can see STP packets are being sent from the MikroTic to the APs via a wireshark sniff on the non Mikrotik AP. I've tested RTSP via the wired side of the hAP and this works fine to detect loops but the WiFi side doesn't. The Mikrotik is currently on a bench and is connected to the same AP on 2 and 5Ghz.
The bridge config is show below:
/interface bridge port
add bridge=bridge1 interface=wlan2 internal-path-cost=11 path-cost=11
add bridge=bridge1 interface=ether1 priority=0x70
add bridge=bridge1 interface=ether2 priority=0x70
add bridge=bridge1 interface=ether3 priority=0x70
add bridge=bridge1 interface=ether4 priority=0x70
add bridge=bridge1 interface=ether5 priority=0x70
add bridge=bridge1 interface=wlan1 internal-path-cost=20 path-cost=20 priority=0x90
Should I be able to use RTSP in this way? I don't want to use OSPF as the devices I need are all on the same subnet.
