路由递归寻址：
RT1的路由条目：
10.1.3.0/24 Static 60 0 10.1.2.2 Ser1/0
10.1.4.0/24 Static 60 0 10.1.2.2 Ser1/0
10.1.5.0/24 Static 60 0 10.1.2.2 Ser1/0
上面路由条目的作用与下面路由条目作用相同，在静态路由只配置下一跳IP地址的情况下，下面路由条目在转发时需要进行递归寻址，转发效率低于上面的路由条目。
10.1.3.0/24 Static 60 0 10.1.2.2 Ser1/0
10.1.4.0/24 Static 60 0 10.1.3.2 Ser1/0
10.1.5.0/24 Static 60 0 10.1.4.2 Ser1/0
路由规则
路由器默认情况下只知道直连的路由信息。
路由器对数据进行精确匹配，即优先匹配子网掩码位数长的路由条目。
缺省路由：
ip route-static 0.0.0.0 0.0.0.0 10.1.99.254 //所有数据均发给网关10.1.99.254
操作：
H3C：ip route-static 与display ip routing-table
Huawei：conf t 全局配置模式
Ip route 与show ip route
