29、，确保在一条链路出现故障后仍能保持网络的连通性，但是两者存在差异，等价静态路由除了提供冗余外，还能提供负载均衡，数据包会被平均在两条链路上传输，而非等价静态路由中只有高优先级低代价的路由是活动的，只有这条路由因为链路故障或接口关闭等原因导致不可用时，低优先级高代价的路由才会被启用。等价静态路由适用于存在多条带宽一样的链路的情况，而非等价静态路由适用于存在多条带宽不同的链路的情况尤其是存在主链路和备份链路的情况。7、配置默认路由拓扑图：RoNetwork_Dept端：sysSystem View: return to User View with Ctrl+Z.H3Csysn RoNetwork
