摘要:This paper introduced the working principle of VRRP Load Balance Technology and technical detail. Through simulation software GNS3 it constructed the Load Balance network, and configured the VRRP technology, which causes the different local area network to data flow load balance through the VRRP technology, when a single point of failure occurs, the gateway can be migrated adaptively without affect the normal use of the network. It provides a flexible and effective solution to implement the load balance lab environment.
