ABSTRACT:
A bridge forwarding method comprises: receiving a frame from an input port, obtaining the input VLAN ID and a destination MAC address of the frame; determining an output port and an output VLAN ID of the frame, and forwarding the frame according to the output port and the output VLAN ID. A bridge forwarding apparatus includes at least one output port used for receiving a frame from more than one VALN, at least one output port used for transmitting the frame to more than one VALN and a forwarding unit, the forwarding unit obtains the input VLAN ID and the destination MAC address in the frame, determines the output port and the output VLAN ID of the frame, and outputs the frame to the corresponding output port. The method and the apparatus of this invention can realize the bridge forwarding of the Ethernet frames between multiple VLANs.
