实验目的:
1、掌握PPPoE的客户端配置方法.
实验拓扑图:
![]()
实验步骤及要求:
1、由于本实验需要模拟ADSL的ISP端的配置。而ISP端的配置并不需要NP学员掌握。因此,本处仅给出配置和简单的解释。
2、拓扑中的R4路由器配置。
R4(config)#interface loopback 0
[stanley1]
R4(config-if)#ip address 202.102.48.140 255.255.255.0
R4(config-if)#ip address 64.35.136.33 255.255.255.0 secondary
R4(config-if)#exit
R4(config)#
R4(config)#interface fastEthernet 0/0
R4(config-if)#pppoe enable
R4(config-if)#no shutdown
[stanley2]
R4(config-if)#exit
R4(config)#
R4(config)#ip dhcp pool cisco
[stanley3]
R4(dhcp-config)#network 211.95.36.0 /24
[stanley4]
R4(dhcp-config)#dns-server 211.95.36.1
[stanley5]
R4(dhcp-config)#exit
R4(config)#
R4(config)#ip dhcp excluded-address 211.95.36.1
[stanley6]
R4(config)#
R4(config)#interface virtual-template 1
R4(config-if)#encapsulation ppp
R4(config-if)#ppp authentication chap
R4(config-if)#peer default ip address dhcp-pool cisco
R4(config-if)#ip address 211.95.36.1 255.255.255.0
R4(config-if)#no shutdown
R4(config-if)#exit
[stanley7]
R4(config)#
R4(config)#vpdn enable
R4(config)#vpdn-group 1
R4(config-vpdn)#accept-dialin
R4(config-vpdn-acc-in)#protocol pppoe
R4(config-vpdn-acc-in)#virtual-template 1
[stanley8]
R4(config-vpdn-acc-in)#exit
R4(config-vpdn)#exit
R4(config)#
R4(config)#username adsl password cisco
[stanley9]
R4(config)#
3、拓扑中R1路由器配置。由于Dynamips目前使用的ATM接口不支持PPPOE,所以只能将R1作为桥接设备,将数据帧桥接给R4,由R4的以太口来处理PPPOE数据帧,下面是R1的桥接配置:
R1(config)#no ip routing
[stanley10]
R1(config)#
R1(config)#interface fastEthernet 0/0
R1(config-if)#bridge-group 1
[stanley11]
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#
R1(config)#interface atM 1/0
R1(config-if)#bridge-group 1
[stanley12]
R1(config-if)#pvc 1/100
R1(config-if-atm-vc)#encapsulation aal5snap
R1(config-if-atm-vc)#exit
[stanley13]
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#
R1(config)#bridge 1 protocol ieee
[stanley14]
R1(config)#exit
R1#
4、配置拓扑中的CPE设备R2路由器:
R2(config)#no ip routing
[stanley15]
R2(config)#
R2(config)#interface fastEthernet 0/0
R2(config-if)#bridge-group 1
R2(config-if)#no shutdown
R2(config-if)#exit
R2(config)#
R2(config)#interface atM 1/0
R2(config-if)#bridge-group 1
R2(config-if)#pvc 2/200
R2(config-if-atm-vc)#encapsulation aal5snap
R2(config-if-atm-vc)#exit
R2(config-if)#no shutdown
R2(config-if)#exit
R2(config)#
R2(config)#bridge 1 protocol ieee
R2(config)#exit
R2#
5、在R2与R1路由器上检测ATM接口,确认ATM可以正常工作:
R2#ping atm interface atM 1/0 2 200
Type escape sequence to abort.
Sending 5, 53-byte end-to-end OAM echoes, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 32/92/240 ms
R2#
R1#ping atm interface aTM 1/0 1 100
Type escape sequence to abort.
Sending 5, 53-byte end-to-end OAM echoes, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 44/100/252 ms
R1#
6、当完成上面ISP端的配置后,则可以在PC2主机上进行测试了,此处的PC2为本地网络里任一主机。PC2的操作系统为Windows XP。
7、在PC2上新建一个网络连接。在连接向导中,点击下一步。如下面所示:
![]()
8、选择“连接到Internet”,如下图所示:
![]()
9、选择“手动设置我的连接” ,点击下一步,如下图所示:
![]()
10、选择“用要求用户我和密码的宽带连接来连接” ,点击下一步,如图所示:
![]()
11、填写ISP名称,此外可以任意填写,如下图所示:
![]()
12、填写相应的PPPoE帐号和密码,如下图所示:
![]()
13、完成新建连接配置。
![]()
14、双击新建的ADSL的PPPoE连接,进行拨号测试,如下图所示:
![]()
15、点击拨号会出现如下信息,指出配置成功,XP的PPPoE客户端可以正确的连接到ADSL的网络。
![]()
16、查看XP客户端的IP配置信息:
C:\>ipconfig /all
PPP adapter NP ADSL:
Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : WAN (PPP/SLIP) Interface
Physical Address. . . . . . . . . : 00-53-45-00-00-00
Dhcp Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 211.95.36.4
[stanley16]

DNS Servers . . . . . . . . . . . : 211.95.36.1
[stanley17]
NetBIOS over Tcpip. . . . . . . . : Disabled
C:\>
17、使用XP主机使用ping命令确认可以连接到Internet网络:
C:\>ping 64.35.136.33
Pinging 64.35.136.33 with 32 bytes of data:
Reply from 64.35.136.33: bytes=32 time=148ms TTL=255
Reply from 64.35.136.33: bytes=32 time=15ms TTL=255
Reply from 64.35.136.33: bytes=32 time=31ms TTL=255
Reply from 64.35.136.33: bytes=32 time=265ms TTL=255
Ping statistics for 64.35.136.33:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 15ms, Maximum = 265ms, Average = 72ms

18、上面的配置是在XP的环境中完成,其主要的优点,就是能够使用XP的PPPoE客户端软件,快速的测试骨干网络的配置的正确性。下面给出了R3路由器的PPPoE客户端以及相关的NAT与DHCP的配置。
19、在R3上配置DHCP用于向客户端分配IP。
R3(config)#
R3(config)#ip dhcp pool local_net
R3(dhcp-config)#network 192.168.1.0 /24
R3(dhcp-config)#default-router 192.168.1.1
R3(dhcp-config)#import all
[stanley18]
R3(dhcp-config)#exit
R3(config)#
R3(config)#interface fastEthernet 1/0
R3(config-if)#ip address 192.168.1.1 255.255.255.0
R3(config-if)#no shutdown
R3(config-if)#exit
20、在R5上配置接口为自动获取IP方式:
R5(config)#interface fastEthernet 1/0
R5(config-if)#ip address dhcp
R5(config-if)#no shutdown
R5(config-if)#exit
R5(config)#exit
21、配置完R5后,稍等片刻,会得到如下IOS提示:
R5#
*Jul 7 18:53:50.639: %DHCP-6-ADDRESS_ASSIGN: Interface FastEthernet1/0 assigned DHCP address 192.168.1.2, mask 255.255.255.0, hostname R5
[stanley19]
R5#
22、查看R5路由器的IP信息:
R5#show ip interface brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES unset administratively down down
FastEthernet1/0 192.168.1.2 YES DHCP up up
[stanley20]
R5#
23、使用PING命令测试网络连接:
R5#ping 192.168.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 12/28/56 ms
R5#
24、配置R3路由器的PPPoE客户端,具体配置如下:
R3(config)#interface fastEthernet 0/0
R3(config-if)#pppoe enable
R3(config-if)#pppoe-client dial-pool-number 1
[stanley21]
R3(config-if)#no shutdown
R3(config-if)#exit
R3(config)#
R3(config)#vpdn enable
R3(config)#
R3(config)#vpdn-group 1
R3(config-vpdn)#request-dialin
[stanley22]
R3(config-vpdn-req-in)#protocol pppoe
R3(config-vpdn-req-in)#exit
R3(config-vpdn)#exit
R3(config)#dialer-list 1 protocol ip permit
[stanley23]
R3(config-if)#
R3(config)#interface dialer 1
[stanley24]
R3(config-if)#
R3(config-if)#encapsulation ppp
R3(config-if)#ppp chap hostname adsl
R3(config-if)#ppp chap password cisco
[stanley25]
R3(config-if)#ip address negotiated
[stanley26]
R3(config-if)#dialer pool 1
[stanley27]
R3(config-if)#dialer-group 1
[stanley28]
R3(config-if)#ip mtu 1496
[stanley29]
R3(config-if)#exit
R3(config)#
25、配置R3路由器的PAT:
R3(config)#interface fastEthernet 1/0
R3(config-if)#ip nat inside
R3(config-if)#exit
R3(config)#
R3(config)#interface dialer 1
R3(config-if)#ip nat outside
R3(config-if)#exit
R3(config)#
R3(config)#access-list 1 permit any
R3(config)#
R3(config)#ip nat inside source list 1 interface dialer 1 overload
R3(config)#
R3(config)#ip route 0.0.0.0 0.0.0.0 dialer 1
[stanley30]
26、在R5上测试,是否可以PING通Internet网络的IP:
R5#ping 202.102.48.140
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 202.102.48.140, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 64/96/128 ms
R5#
R5#ping 64.35.136.33
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 64.35.136.33, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 68/112/148 ms
R5#
27、查看R3路由器的NAT转换表:
R3#show ip nat translations
Pro Inside global Inside local Outside local Outside global
icmp 211.95.36.3:2 192.168.1.2:2 202.102.48.140:2 202.102.48.140:2
icmp 211.95.36.3:3 192.168.1.2:3 64.35.136.33:3 64.35.136.33:3
R3#
28、查看R3的DHCP地址分配信息:
R3#show ip dhcp binding
Bindings from all pools not associated with VRF:
IP address Client-ID/ Lease expiration Type
Hardware address/
User name
192.168.1.2 0063.6973.636f.2d63. Jul 08 2007 06:53 PM Automatic
6130.342e.3066.6563.
2e30.3031.632d.4661.
312f.30
R3#
29、查看PPPoE会话信息:
R3#show pppoe session
Total PPPoE sessions 1
PPPoE Session Information
UID SID RemMAC OIntf Intf Session
LocMAC VASt state
0 2 ca03.0fec.0000 Fa0/0 Vi1 N/A
ca02.0fec.0000 UP
R3#
30、实验完成。
