Cisco PPPoE配置实例（3640路由器接ADSL Modem）

　　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

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.

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
pppoe-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
