静态路由实验

拓扑图

实验步骤

1.按照拓扑完成配置

2.查看R1的路由表,可以看到1.0网段没有和3.0网段的直连路由，无法ping通

[RTA]dis ip routing-table
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Tables: Public
         Destinations : 6        Routes : 6        

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

      127.0.0.0/8   Direct  0    0           D   127.0.0.1       InLoopBack0
      127.0.0.1/32  Direct  0    0           D   127.0.0.1       InLoopBack0
    192.168.1.0/24  Direct  0    0           D   192.168.1.10    GigabitEthernet
0/0/0
   192.168.1.10/32  Direct  0    0           D   127.0.0.1       GigabitEthernet
0/0/0
    192.168.2.0/24  Direct  0    0           D   192.168.2.1     GigabitEthernet
0/0/1
    192.168.2.1/32  Direct  0    0           D   127.0.0.1       GigabitEthernet
0/0/1

3.给R1添加静态路由

[RTA]ip route-static 192.168.3.0 24 192.168.2.10

4.再次查看路由表

[RTA]dis ip routing-table
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Tables: Public
         Destinations : 7        Routes : 7        

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

      127.0.0.0/8   Direct  0    0           D   127.0.0.1       InLoopBack0
      127.0.0.1/32  Direct  0    0           D   127.0.0.1       InLoopBack0
    192.168.1.0/24  Direct  0    0           D   192.168.1.10    GigabitEthernet
0/0/0
   192.168.1.10/32  Direct  0    0           D   127.0.0.1       GigabitEthernet
0/0/0
    192.168.2.0/24  Direct  0    0           D   192.168.2.1     GigabitEthernet
0/0/1
    192.168.2.1/32  Direct  0    0           D   127.0.0.1       GigabitEthernet
0/0/1
    192.168.3.0/24  Static  60   0          RD   192.168.2.10    GigabitEthernet
0/0/1

在实际工作中可能会遇到成百上千条路由表，这个时候就可以在display ip routing-table命令后加上目标ip，快速查看是否存在该路由。

[RTA]dis ip routing-table 192.168.3.1
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Table : Public
Summary Count : 1
Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

    192.168.3.0/24  Static  60   0          RD   192.168.2.10    GigabitEthernet
0/0/1

5.尝试充主机A去Ping服务器，发现还是无法ping成功；只是因为我们只在R1里配置了数据包发送时的路由，回来的路由还没有配置。所以需要在R2上同样配置静态路由。

[RTB]ip route-static 192.168.1.0 24 192.168.2.1

[RTB]dis ip routing-table
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Tables: Public
         Destinations : 7        Routes : 7        

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

      127.0.0.0/8   Direct  0    0           D   127.0.0.1       InLoopBack0
      127.0.0.1/32  Direct  0    0           D   127.0.0.1       InLoopBack0
    192.168.1.0/24  Static  60   0          RD   192.168.2.1     GigabitEthernet
0/0/0
    192.168.2.0/24  Direct  0    0           D   192.168.2.10    GigabitEthernet
0/0/0
   192.168.2.10/32  Direct  0    0           D   127.0.0.1       GigabitEthernet
0/0/0
    192.168.3.0/24  Direct  0    0           D   192.168.3.1     GigabitEthernet
0/0/1
    192.168.3.1/32  Direct  0    0           D   127.0.0.1       GigabitEthernet
0/0/1

6.最后Ping成功
