Router3 的配置清单： <Huawei> system-view [Huawei]sysname Router3 [Router3]interface GigabitEthernet0/0/0 [Router3-GigabitEthernet0/0/0]description To_Router1 [Router3-GigabitEthernet0/0/0]ip address 192.168.11.31 255.255.255.0 [Router3-GigabitEthernet0/0/0]quit [Router3] interface GigabitEthernet0/0/1 [Router3-GigabitEthernet0/0/1]description To_Router2 [Router3-GigabitEthernet0/0/1]ip address 192.168.12.32 255.255.255.0 [Router3-GigabitEthernet0/0/1]quit [Router3]ip route-static 192.168.10.0 255.255.255.0 GigabitEthernet0/0/0 192.168.11.13 [Router3]ip route-static 192.168.20.0 255.255.255.0 GigabitEthernet0/0/1 192.168.12.23

Router4 的配置清单： <Huawei> system-view [Huawei]sysname Router4 [Router4] interface GigabitEthernet0/0/0 [Router4-GigabitEthernet0/0/0]description To_Router1 [Router4-GigabitEthernet0/0/0]ip address 192.168.14.41 255.255.255.0 [Router4-GigabitEthernet0/0/0]quit [Router4]interface GigabitEthernet0/0/1 [Router4-GigabitEthernet0/0/1]description To_Router2 [Router4-GigabitEthernet0/0/1]ip address 192.168.13.42 255.255.255.0 [Router4-GigabitEthernet0/0/1]quit [Router4]ip route-static 192.168.10.0 255.255.255.0 GigabitEthernet0/0/0 192.168.14.14 [Router4]ip route-static 192.168.20.0 255.255.255.0 GigabitEthernet0/0/1 192.168.13.24

①、进行 PC1 到 PC2 的连通测试 可知PC1 至 PC2 已经成功连通。

跟踪 PC1 到 PC2 的路由路径 得到PC1至PC2的路由路径是：PC1→Router1→Router3→Router2→PC2。

假定 Router3 和 Router4 之间，有一台路由器发生故障（如：Router3 发生宕机、掉电等），进行 PC1 到 PC2 的连通测试 PC1至PC2仍然成功连通；但是PC1至PC2的路由路径发生了改变：PC1→Router1→Router4→Router2→PC2。

假定 Router3 在故障排除之后，重新开机上线，那么跟踪 PC1 至 PC2 路由路径。 PC1至PC2的路由路径发生了改变：PC1→Router1→Router3→Router2→PC2；恢复到故障前的路由路径。

假定当前路由路径为：PC1→Router1→Router3→Router2→PC2，当Router3与Router1之间的线路发生故障时，进行PC1到PC2的连通测试、并跟踪路由路径 此时，PC1至PC2是不能连通的。从跟踪路由路径的数据可以看出，当前路由路径为：PC1→Router1→Router4→Router2→PC2，而PC2的应答数据的路由路径则为：PC2→Router2→Router3，因而无法达到PC1。造成链路中断。
