Cisco PPPoE配置实例

实验配置：

1、ADSL PPPoE Client 配置

第一种方法：用PC上创建PPPOE客户端。

第二种方法：用CISCO路由器的以太口进行PPPOE拨号：非固定IP

配置模板：

en

confit t

vpdn enable

vpdn-group pppoe

request-dialin

protocol pppoe

exit

exit

interface ethernet 0/0

no ip address

pppoe enable

pppoe-client dial-pool-number 1

no shutdown //把接口打开

exit

interface Dialer1

ip address negotiated

ip mtu 1492

encapsulation ppp

ppp pap sent-username walkbird password walkbird

dialer pool 1

ip router 0.0.0.0 0.0.0.0 dialer1

2、用cisco路由器做PPPoE Server端配置

en

conf t

hostname Adsl_walkbird

username walkbird password walkbird

vpdn enable

vpdn-group pppoe

accept-dialin

protocol pppoe

virtual-template 1

exit

exit

interface ethernet 0/0

pppoe enable

no shutdown

interface virtual-template 1

mtu 1492 //PPP头部最大传输单元

ip unnumbered loopback //借用地址

peer default ip address pool pppoe_ip_pool

encapsulation ppp

ppp authentication pap

exit

ip local pool pppoe_ip_pool 11.11.11.10 11.11.11.100

interface lookback0

ip address 1.1.1.1 255.255.255.0

no shutdown

exit

三、实验测试

sh ip route

sh ip int brief

debug pppoe event

sh ip int dialer 1

案例二

经典思科1841ADSL的成功设置+DHCP的问题~！急~~！


路由器下面的客户端全是XP。都是设为自动获取IP 地址。

现像是在客户端上IPCONFIG 地址是0。0。0。0
没有获得指定的IP地址，
系统也没有获得169网段的地址。

Cisco Router and Security Device Manager (SDM) is installed on this

device.
This feature requires the one-time use of the username "cisco"
with the password "cisco".

Please change these publicly known initial credentials using SDM or the

IOS CLI.
Here are the Cisco IOS commands.

username privilege 15 secret 0
no username cisco

Replace and with the username and password you

want to use.

For more information about SDM please follow the instructions in the

案例三

假设E0接内网，E1接ADSL上外网

第一步:配置vpdn
vpdn enable(启用路由器的虚拟专用拨号网络---vpnd)

vpdn-group office(建立一个vpdn组,)

request-dialin(初始化一个vpnd tunnel,建立一个请求拨入的vpdn子组,)

protocol pppoe(vpdn子组使用pppoe建立会话隧道)

第二步: 配置路由器连接adsl modem的接口
interface Ethernet1

no ip address

pppoe enable允许以太接口运行pppoe

ppp

oe-client dial-pool-number 1将以太接口的pppoe拨号客户端加入拨号池1

第三步:配置逻辑拨号接口:
interface Dialer1

ip address negotiated从adsl服务商动态协商得到ip地址

ip nat outside为该接口启用NAT

encapsulation ppp为该接口封装ppp协议

dialer pool 1该接口使用1号拨号池进行拨号

dialer-group 1该命令对于pppoe是意义不大的

ppp authentication pap callin启用ppp pap验证

ppp pap sent-username xxxxxxx password 0 yyyyyyy使用已经申请的用户名和口令

第四步:配置内部网络接口
interface Ethernet0(内部网络接口)

ip address 10.1.1.1 255.255.255.0

ip nat inside为该接口启用NAT

第五步:配置路由器为内部网络主机提供dhcp服务
ip dhcp excluded-address 10.1.1.1

ip dhcp pool ABC

import all(导入dns和wins server)

network 10.1.1.0 255.255.255.0

default-router 10.1.1.1

第六步:配置NAT:
access-list 1 permit 10.1.1.0 0.0.0.255

ip nat inside source list 1 interface Dialer1 overload



第七步:配置缺省路由
ip route 0.0.0.0 0.0.0.0 Dialer1
