In the Layer 2 inter-TAC roaming scenario, the STA belongs to the same subnet before and after roaming. The FAP/FAC forwards the messages of the Layer 2 roaming users in the same way as the ordinary newly online users. The messages are directly forwarded in the local network of the FAP/FAC, without the need to be forwarded back to the HAP/HAC through the inter-WAC tunnel.
