I have a problem in my networ that runs with bridge configuration in the devices.
The first image (network.png) shows the network topology (but imagine more 30 sites in the network and same bridge).
The link comes to a site and goes to a MK (RB450g) that filter layer2 and layer3 (accept APs mac and IP, accpet pppoe-dicovery and session, drop the rest).
The second image (bridge_layer2_fw.png) show the RB450g and what is happening: in each bridge port (APs), there is about 4mbps of like a bridge traffic that is not provided by each AP, and this disturbs because of this traffic together and because it's unnecessary.
The packet sniff of this data shows just pppoe-sessions, but session of some clients that is not working on this site.
How can I stop this flood data of the bridge?
