华为eNSP静态路由配置实验——多网段互联与默认路由应用一、实验目的掌握静态路由的配置方法。理解下一跳地址与出接口的区别。掌握默认路由的配置方法。实现多个网段之间的互联互通。学会利用路由表分析网络故障。二、实验拓扑PC1 | 192.168.10.0/24 | R1----------------R2----------------R3 GE0/0/1 GE0/0/1 GE0/0/1 10.0.12.0/30 10.0.23.0/30 | 192.168.30.0/24 | PC2三、IP地址规划R1接口IP地址G0/0/0192.168.10.1/24G0/0/110.0.12.1/30R2接口IP地址G0/0/010.0.12.2/30G0/0/110.0.23.1/30R3接口IP地址G0/0/010.0.23.2/30G0/0/1192.168.30.1/24PC地址设备IP地址网关PC1192.168.10.10192.168.10.1PC2192.168.30.10192.168.30.1四、基础配置1、配置R1Huaweisystem-view [Huawei]sysname R1 [R1]interface GigabitEthernet0/0/0 [R1-GigabitEthernet0/0/0]ip address 192.168.10.1 24 [R1]interface GigabitEthernet0/0/1 [R1-GigabitEthernet0/0/1]ip address 10.0.12.1 30 [R1]quit2、配置R2Huaweisystem-view [Huawei]sysname R2 [R2]interface GigabitEthernet0/0/0 [R2-GigabitEthernet0/0/0]ip address 10.0.12.2 30 [R2]interface GigabitEthernet0/0/1 [R2-GigabitEthernet0/0/1]ip address 10.0.23.1 30 [R2]quit3、配置R3Huaweisystem-view [Huawei]sysname R3 [R3]interface GigabitEthernet0/0/0 [R3-GigabitEthernet0/0/0]ip address 10.0.23.2 30 [R3]interface GigabitEthernet0/0/1 [R3-GigabitEthernet0/0/1]ip address 192.168.30.1 24 [R3]quit五、测试直连网络查看接口状态display ip interface brief结果应显示Interface IP Address/Mask GigabitEthernet0/0/0 up GigabitEthernet0/0/1 up测试邻居连通性R1ping 10.0.12.2R2ping 10.0.23.2若全部成功说明直连链路正常。六、配置静态路由R1配置到192.168.30.0网段的路由[R1]ip route-static 192.168.30.0 24 10.0.12.2R3配置到192.168.10.0网段的路由[R3]ip route-static 192.168.10.0 24 10.0.23.1R2配置双向静态路由[R2]ip route-static 192.168.10.0 24 10.0.12.1 [R2]ip route-static 192.168.30.0 24 10.0.23.2七、验证路由表查看路由表display ip routing-tableR1显示Routing Tables: Public Destination/Mask Proto 192.168.10.0/24 Direct 10.0.12.0/30 Direct 192.168.30.0/24 Static其中Static表示静态路由学习得到。八、配置默认路由提高实验难度实际企业网络中不会为每个网段单独配置路由。假设R1连接的是总部网络。R2配置默认路由[R2]ip route-static 0.0.0.0 0 10.0.12.1R3配置默认路由[R3]ip route-static 0.0.0.0 0 10.0.23.1查看display ip routing-table可看到0.0.0.0/0 Static九、浮动静态路由企业级重点企业网络经常配置主备链路。假设R1 R2 \ / \ / R3正常走R2。当R2故障后自动切换到R3。主路由[R1]ip route-static 192.168.30.0 24 10.0.12.2默认优先级Preference 60备份路由[R1]ip route-static 192.168.30.0 24 10.0.13.2 preference 100查看display ip routing-table正常情况下只学习主路由主链路故障后自动切换备用路由这就是浮动静态路由。十、实验验证PC1 Ping PC2ping 192.168.30.10结果Reply from 192.168.30.10查看路由追踪tracert 192.168.30.10输出192.168.10.1 10.0.12.2 10.0.23.2 192.168.30.10数据经过PC1 → R1 → R2 → R3 → PC2十一、常见故障排查1. 接口未开启查看display ip interface brief状态必须up/up2. 路由配置错误查看display current-configuration检查ip route-static命令是否正确。3. 网关配置错误PC必须配置正确网关PC1 192.168.10.1 PC2 192.168.30.14. 返回路由缺失很多同学只配置单向路由。例如R1能到R3但R3回不到R1因此必须配置双向路由。十二、实验总结本实验通过三台路由器搭建企业级网络环境实现了✅ 多网段互联通信✅ 静态路由配置✅ 默认路由配置✅ 浮动静态路由配置✅ 路由表查看与分析✅ 故障排查方法
