Abstract

The invention discloses message processing method and device and network equipment. The method comprises the steps of: receiving an internet protocol (IP) message comprising message identification information; when address records stored in the established address record list are inquired, and the address records comprise message identification information same as that in the IP message, acquiring MAC address information of the next hop from the address records; replacing the MAC head information of the IP message in accordance with the MAC address information of the next hop to generate the processed IP message; and sending the processed IP message through the acquired output information. The invention does not need acquiring the MAC address information of the next hop from address resolution protocol (ARP) records so as to avoid network communication interruption caused by ARP spoofing.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of network communication, and in particular to a message processing method, device and network equipment. Background technique [0002] Address Resolution Protocol (Address Resolution Protocol, hereinafter referred to as: ARP) is a protocol for resolving addresses. The ARP can resolve the IP address of the network layer of the IP message into a Media Access Control (Media Access Control, MAC for short) address of the physical layer, so that the IP message can be sent through the Ethernet. [0003] The key to the efficient operation of ARP is that the network device is equipped with an ARP cache. The ARP record in the ARP cache stores the ARP entries of other network devices. The ARP entry includes the IP address of the sender in the ARP message sent by other network devices. and the MAC address of the sending end, wherein the IP address of the sending end is the IP address of other...
