Abstract

Embodiments of the present invention provide a message forwarding method, equipment and network device, wherein the message forwarding method includes the following steps: a layer 3 routing table is queried, according to the destination internet protocol (IP) address of a received message, to acquire the next-hop identification information; an address resolution protocol (ARP) table is queried, according to the next-hop identification information, to acquire the next-hop media access control (MAC) address corresponding to the next-hop identification information, wherein the ARP table is composed of the next-hop identification information and the next-hop MAC address corresponding to the next-hop identification information; a layer 2 forwarding table is queried, according to the next-hop MAC address, to acquire the exit port information corresponding to the next-hop MAC address; the message is forwarded out via the exit port corresponding to the exit port information. By applying the technical solution of the present invention to forward the message, the instantaneous busy problem of the device and the problem of the traffic interruption can be solved, wherein the problems are caused by that a large number of ARP Miss messages and ARP request messages are generated when the port switch in a virtual local area network (VLAN) occurs in the prior art. Therefore, the forwarding efficiency of the message is improved.

Description

technical field [0001] Embodiments of the present invention relate to network communication technologies, and in particular to a message forwarding method, device and network equipment. Background technique [0002] The existing three-layer switch binds physical ports in the same virtual local area network (Virtual Local Area Network; referred to as: VLAN) as a virtual port (VLANIF), and configures an Internet Protocol (Internet Protocol; referred to as: IP) address for the virtual port. , Media Access Control (Media Access Control; abbreviated as: MAC) address, etc. to implement Layer 3 forwarding. [0003] The Layer 3 forwarding process based on VLANIF is as follows: when the forwarding module receives a packet, it first searches the Layer 3 routing table according to the destination IP address of the packet, obtains the outbound interface information and the next-hop IP address corresponding to the destination IP The outbound interface information and the next hop IP add...
