Which of the following descriptions about the four forwarding models of WLAN roaming traffic are correct? (Multiple choice)
The correct answer is A. The difference between direct forwarding in Layer 3 roaming and tunnel forwarding in Layer 3 roaming is whether the packet needs to be returned to the HAP C. During the forwarding of the Layer 3 roaming tunnel, if the STA wants to access the atomic network, it needs to return the message to the HAP D. The difference between Layer 2 roaming forwarding and Layer 3 roaming forwarding is whether the subnet before and after STA roaming is the same subnet. See the full explanation below for the reasoning.

Options
- AThe difference between direct forwarding in Layer 3 roaming and tunnel forwarding in Layer 3 roaming is whether the packet needs to be returned to the HAP
- BThere is no difference between direct forwarding in layer 2 roaming and tunnel forwarding in layer 2 roaming, both are forwarded directly in the local network of the AP-VAP
- CDuring the forwarding of the Layer 3 roaming tunnel, if the STA wants to access the atomic network, it needs to return the message to the HAP
- DThe difference between Layer 2 roaming forwarding and Layer 3 roaming forwarding is whether the subnet before and after STA roaming is the same subnet
