Broadcast Storm avoiding

RouterOS Wireless Networking

Hi,
I just need some info and tell me where I am wrong.

A broadcast can only happen on a lv2 network, that I know.
If I got 3 UBNT sectors connecting to a MT1100 RB on ports eth1, eth2 and eth3 where the UBNT is the AP and the MT only does the PPPoE.
The ports are not bridged and I got a PPPoe server running on each interface. None of the AP’s are in the same subnet and they are in bridge mode.
The servers are of course all using the same profiles and pools.

Will this prevent a broadcast storm to affect all ports or will it be isolated to a port?
Or will it be better if I use split-horizon functionality to prevent ports to talk to each other?

Thanks

Are you using client isolation? That would mitigate a lot for you, you should not get a storm across all ports though unless you add the ports to a bridge and then have a single pppoe server on the bridge.
