When Layer 2 isolation is disabled, Layer 2 bridging can be implemented directly if two users require Layer 2 bridging. They do not need to send the packets to the upper-layer gateway to implement the Layer 3 bridging.

Layer 2 bridging is supported by EPON, Huawei GPBC, and Huawei GPBD boards only. In addition, these boards must cooperate with the Huawei SCUL board to implement Layer 2 bridging.
