Method and routing device for implementing VRRP load balance

Abstract

The invention provides a method and a route device thereof for realizing the virtual router redundant protocol (VRRP) loading balance. The virtual router comprises a plurality of routing devices. Default gateway IP addresses of clients at the same network segment are configured into the virtual IP address of the virtual router. In the method, the virtual router chooses a main route device as a self-distributing virtual MAC address, distributes different virtual MAC addresses to other routing devices after receiving virtual MAC distributing request messages that are sent by other routing devices and sends the addresses to other routing devices by address responding messages. After address analyzing requests from the clients are received, the virtual MAC addresses which are distributed to the routing devices of the virtual router are carried in the address analyzing response to be reverted to the clients. Therefore, the configuration of VRRP is simplified and the dynamic VRRP loading balance is realized.

Description

Method and routing device for realizing VRRP load balancing technical field The invention relates to a network communication technology, in particular to a method and a routing device for realizing virtual router redundancy protocol (VRRP, Virtual Router Redundancy Protocol) load balancing. Background technique When realizing the communication between the client and the external network, the same default gateway is usually set for all the clients in the same network segment, that is, the default route with the same gateway as the next hop is configured, and the packets sent by the client to other network segments It will be sent to the gateway of the next hop through the default route, and then forwarded by the gateway. However, when the gateway fails, all clients in this network segment that use the gateway as the default route will not be able to communicate with the external network. Although the default route provides convenience for users to configure and operate, it ...

AI Technical Summary

Problems solved by technology

However, the way to realize VRRP load balancing in the prior art needs to use multiple routing devices to configure different virtual routers and configure different virtual IP addresses for each virtual router, and configure different virtual routers as default gateways for each client. Obviously, the configuration is very complicated in the presence of a large number of clients

Moreover, since the above load balancing method is based on the pre-configured static configuration, dynamic load balancing cannot be achieved
