Abstract

This application provides a method and device for updating a MAC address table, which are applied to network devices, including: when the device is an edge device, if it is determined that the network topology changes, the local MAC address table is not cleared; The IP address and the MAC address of the terminal device connected to the port construct a gratuitous ARP message; send the gratuitous ARP message through the non-edge port; when receiving the gratuitous ARP message sent by other edge devices, based on the gratuitous ARP message The document updates the MAC address table. The technical scheme of the present application can avoid long-term forwarding interruption among hosts in the network, and optimize the forwarding performance of network equipment.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for updating a MAC address table. Background technique [0002] With the development of information technology, the forwarding performance requirements of network equipment are getting higher and higher. In a large-scale Layer 2 forwarding network, physical loops at the data link layer in the LAN can be eliminated based on STP (Spanning Tree Protocol, Spanning Tree Protocol). When there are multiple VLANs (Virtual Local Area Network, virtual local area network) in the two-layer forwarding network, the messages of different VLANs can be forwarded according to their respective paths based on MSTP (Multiple Spanning Tree Protocol, Multiple Spanning Tree Protocol). In the same VLAN, when a network device detects a network topology change, it can notify other network devices of the network topology change through a BPDU (Bridge Protocol Data U...
