Problems solved by technology

During this learning process, since it takes time for the network device to complete the addition of the new ARP table, some packets transmitted by the device will inevitably be discarded during this process.
Moreover, the ARP refresh processing and maintenance time of the aging table by the network device also consumes system resources.

Abstract

The invention provides a network device address resolution protocol address refreshing method and device. Network devices include the local network device and the opposite end network device, wherein the local network device comprises a local ARP table, and the opposite end network device comprises an opposite end ARP table. The method includes the steps that when faults happen to the port of the local network device and are eliminated, the local network device sends an ARP request message to the corresponding opposite end network device in the local ARP table, the local network device receives an ARP response message retuned by the opposite end network device for the ARP request message, and the local network device refreshes the local ARP table according to the ARP response message. According to the network device address resolution protocol address refreshing method and device, running expenses of the network devices are reduced, network management complexity is reduced, and stability of a system is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for refreshing an ARP address of a network device, and a device for refreshing an ARP address of a network device. Background technique [0002] IPv4 (Internet Protocol version 4, Internet Protocol version4) is a widely used protocol that forms the cornerstone of today's Internet technology. The IPv4 ARP (Address Resolution Protocol, Address Resolution Protocol) follows the standard ARP aging process. When the aging condition is met, the network device must first delete the ARP table. refer to figure 1 A schematic diagram of an APR learning process in the prior art shown after reaching the aging condition. When the corresponding device is found by querying the routing table, ARP will not be triggered until network device 1 forwards new data to network device 2 request, and send it to network device 1, and network device 2 can add a new ARP table after netw...
