摘　　要：局域网接入到Internet网络系统中,客户端访问Internet的数据包先转到三层交换机,三层交换机设置默认路由转到出口路由器,再由出口路由器转向Internet。如果局域网的三层交换机数量较多,每个三层交换机都需要设置默认路由指向出口路由器,配置上显得比较麻烦。本文针对某一局域网接入Internet的网络方案,论述注入默认路由技术,分析注入默认路由工作过程,实现局域网出口路由器配置默认路由并且将默认路由注入到局域网,提高了网络的稳定性和配置方法的有效性。In Local Area Network(LAN) access to the Internet, data packets of client accessing the Internet are transferred to layer-3 switch first, layer-3 switch then sets a default route to an export router, after that data packets are transferred to the Internet from export router. If the number of layer-3 switches in LAN is large, each layer-3 switch would need to set a default route to export router, which makes configuration rather cumbersome. Aiming at a LAN access to the Internet network scheme, the paper discusses a default routing injection technology, analyzes the injection default routing work process, implements the default route with the LAN export router and injects the default route into LAN, which improves the stability and effectiveness of network configuration.
