实验名称：静态路由的配置

实验内容

    使用Boson NetSim软件模拟出路由器的环境，并配置静态路由。

    使用Boson NetSim Designer软件设计一个含有三个路由器和两个PC机的网络环境，两个PC机器分别连接到两个路由器（1750）上，这两个1750型路由器连接到同一个2611型路由器上（使用串口）。如图：

    在PC1上使用ipconfig指令配置IP：

C:>ipconfig /ip 192.168.0.2 255.255.255.0
C:>ipconfig /dg 192.168.0.1
C:>ipconfig
  Boson BOSS 5.0 IP Configuration
     Ethernet adapter Local Area Connection:
        IP Address. . . . . . . . . . . . : 192.168.0.2
        Subnet Mask . . . . . . . . . . . : 255.255.255.0
        Default Gateway . . . . . . . . . : 192.168.0.1

    在PC2上使用winipcfg进行类似配置：

    分别配置三个路由器的IP地址（#后为注释，下同）：

# Router1：
Router>enable
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface e0
Router(config-if)#ip address 192.168.0.1 255.255.255.0
Router(config-if)#no shutdown
%LINK-3-UPDOWN: Interface Ethernet0, changed state to up
Router(config-if)#exit
Router(config)#interface s0
Router(config-if)#ip address 192.168.2.1 255.255.255.0
Router(config-if)#no shutdown
%LINK-3-UPDOWN: Interface Serial0, changed state to up
Router(config-if)#exit

# Router2：

Router>enable

Router#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#interface e0

Router(config-if)#ip address 192.168.1.1 255.255.255.0

Router(config-if)#no shutdown

%LINK-3-UPDOWN: Interface Ethernet0, changed state to up

Router(config-if)#exit

Router(config)#interface s0

Router(config-if)#ip address 192.168.3.2 255.255.255.0

Router(config-if)#no shutdown

%LINK-3-UPDOWN: Interface Serial0, changed state to up

Router(config-if)#exit

# Router3：

Router>enable

Router#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#interface s0

Router(config-if)#ip address 192.168.2.3 255.255.255.0

Router(config-if)#no shutdown

%LINK-3-UPDOWN: Interface Serial0, changed state to up

Router(config-if)#exit

Router(config)#interface s1

%LINK-3-UPDOWN: Interface Serial0, changed state to down

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to down

Router(config-if)#ip address 192.168.3.3 255.255.255.0

Router(config-if)#no shutdown

%LINK-3-UPDOWN: Interface Serial1, changed state to up

Router(config-if)#exit

Router(config)#exit

%LINK-3-UPDOWN: Interface Serial1, changed state to down

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1, changed state to down

    使用show controllers指令查看各个路由是DCE还是DTE：

# Router3：
Router#show controllers

HD unit 0, idb = 0x1AE828, driver structure at 0x1B4BA0
buffer size 1524  HD unit 0,V.35 DCE cable
cpb = 0x7, eda = 0x58DC, cda = 0x58F0
RX ring with 16 entries at 0x4075800

HD unit 0, idb = 0x1AE828, driver structure at 0x1B4BA0
buffer size 1524  HD unit 0,V.35 DCE cable
cpb = 0x7, eda = 0x58DC, cda = 0x58F0
RX ring with 16 entries at 0x4075800
……

# Router1：
Router#show controllers

HD unit 0, idb = 0x1AE828, driver structure at 0x1B4BA0
buffer size 1524  HD unit 0,V.35 DTE cable
cpb = 0x7, eda = 0x58DC, cda = 0x58F0
RX ring with 16 entries at 0x4075800

# Router 2：
Router>show controllers

HD unit 0, idb = 0x1AE828, driver structure at 0x1B4BA0
buffer size 1524  HD unit 0,V.35 DTE cable
cpb = 0x7, eda = 0x58DC, cda = 0x58F0
RX ring with 16 entries at 0x4075800

    在Router3上配置时钟频率：

Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface s0
Router(config-if)#clock rate 64000
%LINK-3-UPDOWN: Interface Serial0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to up
Router(config-if)#exit
Router(config)#interface s1
Router(config-if)#clock rate 64000
Router(config-if)#exit
%LINK-3-UPDOWN: Interface Serial1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1, changed state to up

    在3个路由器上分别配置转发规则：

# Router1
Router(config)#ip route 192.168.1.0 255.255.255.0 192.168.2.3
Router(config)#ip route 192.168.3.0 255.255.255.0 192.168.2.3

# Router2
Router(config)#ip route 192.168.0.0 255.255.255.0 192.168.3.3
Router(config)#ip route 192.168.2.0 255.255.255.0 192.168.3.3

# Router3
Router(config)#ip route 192.168.0.0 255.255.255.0 192.168.2.1
Router(config)#ip route 192.168.1.0 255.255.255.0 192.168.3.2

    检查配置，在PC1上尝试traceroute到PC2：

C:>tracert 192.168.1.2

Tracing the route to 192.168.1.2

 2 192.168.2.3 20 msec 16 msec 16 msec
 3 192.168.3.2 20 msec 16 msec 16 msec
 4 192.168.1.2 20 msec 16 msec *
