cisco 1841 pppoe设置案例二
经典思科1841 ADSL的成功设置+DHCP
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。

#p#cisco 1841 pppoe设置案例三
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
