A method and a device for sending a packet based on Tunneling Protocol used in Layer 2 are provided. Specifically, when a traffic flow needs to be sent from a network side to a client via QinQ termination equipment in which the tunneling protocol used in Layer 2 is used , obtaining forwarding address information corresponding to the client by searching a Dynamic Host Configuration Protocol (DHCP) snooping binding table according to Internet Protocol (IP) address information of the client in a packet of the traffic flow. Thus, ARP requests do not need to be sent by traversing all VLAN tags which are configured on a QinQ termination interface. The packet of the traffic flow can be sent to the client according to the obtained forwarding address information. Therefore, blockage in the network channel caused by sending a large number of ARP packets is prevented, and network resources are saved. Meanwhile, the operation load of connected switching equipment is effectively reduced, and the network operation quality is improved.
