Problems solved by technology

However, in the VRRP network topology, there are active and standby links. Before the standby link is used, there is no data exchange, so that the MAC address forwarding table has no record of the standby port, which leads to the discovery through the MAC address forwarding table. Method fails to discover alternate links correctly

Abstract

The invention provides a method, device and equipment for discovering network topology of a virtual router redundancy protocol. The method includes: obtaining device information in a virtual router redundancy protocol VRRP network, the device information including at least an identifier of the device and an address resolution protocol (ARP) table of the device; determining according to the identifier of the device and the address resolution protocol table of the device All links between devices in the VRRP network. The device includes: an obtaining module and a determining module. The device comprises the above-mentioned means. The solution provided by the invention effectively overcomes the problem in the prior art that the standby link between devices cannot be automatically discovered.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device and device for discovering a virtual router redundancy protocol (Virtual Router Redundancy Protocol, VRRP for short) network topology. Background technique [0002] With the rapid development of computer network technology, people rely more and more on the network for daily work and life. Network resilience, redundancy, and load balancing capabilities have become key features of today's networks. For this reason, the VRRP protocol came into being. This protocol is applied to Layer 3 switches and routers on the statically configured default gateway, providing faster and more effective redundant fault tolerance for terminal systems that rely on the default gateway for WAN access or access to other LAN domains and load balancing capabilities. The VRRP design adopts the active-standby mode to ensure that when the main routing de...
