完成拓扑结构

Router(config)#int g0/1
Router(config-if)#ip add 10.1.1.1 255.255.255.0
Router(config-if)#no shutdown。

配置g口路由器ip,使主机可以连通路由器

Router(config)#int s0/2/0
Router(config-if)#ip add 172.1.1.2 255.255.255.0
Router(config-if)#clock rate 2000000
Router(config-if)#no shutdown

配置R1 s0/2/0串口ip,设置时钟率

Router(config)#int s0/2/0
Router(config-if)#ip add 172.1.1.1 255.255.255.0
Router(config-if)#no shutdown

配置R0 s0/2/0,路由器串口两边都要配置

Router(config)#int s0/2/1
Router(config-if)#ip add 172.1.2.1 255.255.255.0
Router(config-if)#clock rate 2000000
Router(config-if)#no shutdown

配置中转路由R0的另一个串口

时钟配置要向水一样顺时针

相同方法配置R2

配置静态路由

同一个路由下默认有直连路由,其下三个网络可以相互连通

不知道下一条的地址,可以用出入口来配置静态路由

比如左边的网络想要访问到172.1.2.1 已知出口是s0/2/0,可以这样写
Router(config)#ip route 172.1.2.0 255.255.255.0 s0/2/0


配置R1

Router(config)#ip route 172.1.2.0 255.255.255.0 s0/2/0
%Default route without gateway, if not a point-to-point interface, may impact performance
Router(config)#ip route 192.168.1.0 255.255.255.0 s0/2/0
%Default route without gateway, if not a point-to-point interface, may impact performance
Router(config)#ip route 192.168.2.0 255.255.255.0 s0/2/0
%Default route without gateway, if not a point-to-point interface, may impact performance

配置R2

Router(config)#ip route 172.1.1.0 255.255.255.0 s0/2/1
%Default route without gateway, if not a point-to-point interface, may impact performance
Router(config)#ip route 10.1.1.0 255.255.255.0 s0/2/1
%Default route without gateway, if not a point-to-point interface, may impact performance
Router(config)#ip route 10.1.2.0 255.255.255.0 s0/2/1
%Default route without gateway, if not a point-to-point interface, may impact performance

配置R0 注意左边网络的出口是s0/2/0,右边网络的出口是s0/2/1

Router(config)#ip route 10.1.1.0 255.255.255.0 s0/2/0
%Default route without gateway, if not a point-to-point interface, may impact performance
Router(config)#ip route 10.1.2.0 255.255.255.0 s0/2/0
%Default route without gateway, if not a point-to-point interface, may impact performance
Router(config)#ip route 192.168.1.0 255.255.255.0 s0/2/1
%Default route without gateway, if not a point-to-point interface, may impact performance
Router(config)#ip route 192.168.2.0 255.255.255.0 s0/2/1
%Default route without gateway, if not a point-to-point interface, may impact performance

设置成功!

附加

下一跳 命令和出入口差不多 只在最后有所区别

ip route 172.1.1.0 255.255.255.0 出入口
ip route 172.1.1.0 255.255.255.0 下一跳ip地址
