Abstract: A line card of a virtual extensible local area network (VXLAN) gateway receives a data packet, determines to perform a layer-three forwarding to the data packet, takes a fabric board of a category as a destination fabric board, which matches with a value of a set bit position of a destination internet protocol (IP) address of the data packet, and transmits the data packet to the destination fabric board. Subsequently, after receiving the data packet, when determining to perform the layer-three forwarding to the data packet, the destination fabric board searches in address resolution protocol (ARP) entries stored therein for an ARP entry, which matches with the destination IP address of the data packet, and cooperates with a first destination line card associated with the output port in the ARP entry searched out to forward the data packet.
