Method for performing communication among virtual router redundancy protocol (VRRP) routers and routers

Abstract

The invention provides a method for performing communication among virtual router redundancy protocol (VRRP) routers and the routers. The method comprises the following steps of: judging whether a VRRPv2 router and a VRRPv3 router exist in the same VRRP group or not according to the acquired VRRP information, wherein the VRRP information comprises identifiers of the VRRP routers, an identifier ofthe VRRP group and a VRRP version; and if so, inhibiting the transmission of a VRRPv3 message in the preset time and otherwise, inhibiting the transmission of a VRRPv2 message in the preset time, wherein each router comprises a judgment module and an inhibition module. The method effectively solves the problem of wasting of network bandwidth and equipment resources caused by that the VRRPv3 router must transmit the VRRPv2 message and the VRRPv3 message at the same time in the prior art, so the network bandwidth and the equipment resources are saved and the multi-MASTER problem under the coexistence of the VRRPv2 router and the VRRPv3 router is solved.

Description

technical field [0001] The embodiment of the present invention relates to the field of network technology, and in particular to a method for communicating between routers of a virtual routing redundancy protocol and a router. Background technique [0002] Virtual Router Redundancy Protocol (Virtual Router Redundancy Protocol, referred to as: VRRP) is a selection protocol, which can dynamically assign the responsibility of a virtual router to one of multiple VRRP routers in a VRRP group on the LAN. Multiple routers in a VRRP group are mapped to a virtual router, and VRRP ensures that there is only one router sending data packets on behalf of the virtual router at the same time. The VRRP router that controls the IP addresses of the virtual routers is called the active router, and it is responsible for forwarding packets to these virtual IP addresses. Once the main router is unavailable, the backup router can perform function switching without affecting internal and external d...
