多出口NAT策略路由案例·已完成·GNS3 通过配置实现: 宿舍区访问互联网使用电信出口.教学区使用联通出口 任何一条链路故障,能够自动切换 宿舍区和教学区均使用路由器出口地址做PAT 配置思路: 基础拓扑搭建. 划分VLAN,配置access/trunk/SVI,IP 地址 配置内网路由(汇聚于核心跑OSPF) 规划外网路由与NAT 如何实现,让宿舍区192. 168.10.0走电信 如何实现,让教学区192. 168.20.0走联通 如何让走电信出口的,利用电信的NAT地址池/电信接口地址做PAT(为何要这样?因为如果你使用了电信的NAT地址从联通出去了,数据包可以回来吗?如果你访问的电信的地址,网通ISP没有这条目的地的路由就无法通信) 我的博文里有配置步骤可以参考http://t.csdn.cn/84TP3
