                                             實現GNS的類比路由器串連Internet

 

1、環境: XP 系統，GNS3.0.7.2 整合SecureCRT（也可以沒有SecureCRT）

   準備：在XP系統下添加Loopback adapter 虛擬網卡，一個ADSL撥號連線

 

2、網路連接配置：

    650) this.width=650;" src="http://hi.csdn.net/attachment/201010/20/0_1287560229GIQc.gif" />

 

 

   

7、選中R1然後按右鍵，單擊“開始“，接著在選中R1按右鍵，單擊“Console”出現與GNS整合的SecureCRT配置控制台（如果沒有整合SecureCRT的話會出現一個dos一樣的控制台）:

    650) this.width=650;" src="http://hi.csdn.net/attachment/201010/20/0_1287561273Mc10.gif" />

 

 

 

 3、接著開啟運行，輸入services.msc出現如下介面:

       650) this.width=650;" src="http://hi.csdn.net/attachment/201010/20/0_1287560406HGll.gif" />

  

然後找到下面服務，並確定這些服務已啟動，否則設定他們為已啟動。

DHCP  Client 設為已啟動

DNS Client 設為已啟動

Windows Firewall / Internet Connection Sharing(ICS) 設為已啟動.

 

 

4、開啟網路連接，雙擊“寬頻連線勾上”任何使用此電腦的人“接著填上密碼，然後，選擇“屬性”然後選擇“進階“ 進行設定：

       650) this.width=650;" src="http://hi.csdn.net/attachment/201010/20/0_1287560601NczD.gif" alt="http://hi.csdn.net/attachment/201010/20/0_1287560601NczD.gif" height="370" width="347" />

       650) this.width=650;" src="http://hi.csdn.net/attachment/201010/20/0_1287560675emMP.gif" alt="http://hi.csdn.net/attachment/201010/20/0_1287560675emMP.gif" height="443" width="371" />

       650) this.width=650;" src="http://hi.csdn.net/attachment/201010/20/0_1287560730RFQx.gif" alt="http://hi.csdn.net/attachment/201010/20/0_1287560730RFQx.gif" height="411" width="361" />

 

    完成設定後查看網路連接變化：

  650) this.width=650;" src="http://hi.csdn.net/attachment/201010/20/0_1287560806jVJY.gif" alt="http://hi.csdn.net/attachment/201010/20/0_1287560806jVJY.gif" height="380" width="553" />

 

5、完成以上步驟後開啟GNS3.0.7.2構建拓撲如下：

 

650) this.width=650;" src="http://hi.csdn.net/attachment/201010/20/0_1287560919nhM6.gif" alt="http://hi.csdn.net/attachment/201010/20/0_1287560919nhM6.gif" height="313" width="553" />

 

配置Cloud “Loopback”，按右鍵“Loopback”選擇“配置“，按順序進行以下操作即可：

 

 650) this.width=650;" src="http://hi.csdn.net/attachment/201010/20/0_1287561031CsNS.gif" alt="http://hi.csdn.net/attachment/201010/20/0_1287561031CsNS.gif" height="417" width="553" />

 

進行裝置串連，單擊GNS的工具列的“添加串連”按鈕，接著用滑鼠把裝置串連，接著再按“show   interface  names”按鈕，如：

650) this.width=650;" src="http://hi.csdn.net/attachment/201010/20/0_1287561173diO7.gif" alt="http://hi.csdn.net/attachment/201010/20/0_1287561173diO7.gif" height="273" width="553" />

 

 

6、選中R1然後按右鍵，單擊“開始“，接著在選中R1按右鍵，單擊“Console”出現與GNS整合的SecureCRT配置控制台（如果沒有整合SecureCRT的話會出現一個dos一樣的控制台）:

650) this.width=650;" src="http://hi.csdn.net/attachment/201010/20/0_1287561273Mc10.gif" alt="http://hi.csdn.net/attachment/201010/20/0_1287561273Mc10.gif" height="387" width="553" />

 

 

 

7、在SecureCRT裡對R1進行配置.命令如下：

Router>en

Router#conf t

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

Router(config)#host R1

R1(config)#enable pass cisco

R1(config)#line con 0

R1(config-line)#pass cisco

R1(config-line)#login

R1(config-line)#logg synchronous

R1(config-line)#no exec-timeout

R1(config-line)#line vty 0 15

R1(config-line)#pass cisco

R1(config-line)#login

R1(config-line)#logg syn

R1(config-line)#no exec-timeout

R1(config-line)#exit

R1(config)#int fa0/0

R1(config-if)#ip add 192.168.0.2 255.255.255.0

R1(config-if)#no shutdown

R1(config-if)#

*Mar  1 00:05:53.659: %LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up

*Mar  1 00:05:54.659: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

R1(config-if)#end

R1#

*Mar  1 00:07:06.071: %SYS-5-CONFIG_I: Configured from console by console

R1#ping 192.168.0.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.0.1, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 24/41/48 ms

R1#

 

 

8、測試ping外網發現失敗：

R1#ping www.baidu.com

Translating "www.baidu.com"...domain server (255.255.255.255)

% Unrecognized host or address, or protocol not running.

 

R1#ping google.com

Translating "google.com"...domain server (255.255.255.255)

% Unrecognized host or address, or protocol not running.

R1#

 

9、添加預設路由

R1#conf t

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

R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.0.1

R1(config)#exit

 

10、最後測試成功：

R1#ping www.baidu.com

Translating "www.baidu.com"...domain server (255.255.255.255) [OK]

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 220.181.6.18, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 72/96/120 ms

 

R1#ping www.google.com

Translating "www.google.com"...domain server (255.255.255.255) [OK]

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 66.249.89.104, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 72/105/144 ms
