Behavior of the “All APs on This Subnet” wireless client isolation option

When AP 1 and AP 2 are using the “This AP Only” option, wireless traffic between STA 1 and STA 2 is blocked by AP 1, whereas wireless traffic between STA 2 and STA 3 (which are associated with different APs) is still allowed. If the “All APs in This Subnet” option is used as shown in the above figure, AP 1 and AP 2 communicate with each other via an inter-AP protocol to share their STA association information to block wireless traffic among all the STAs.
