Cisco路由器的ADSL modem配置详解你还在为Cisco路由器的ADSL modem配置详解而烦恼么?不用担心，接下来是小编为大家收集的Cisco路由器的ADSL modem配置详解，欢迎大家阅读：Cisco路由器的ADSL modem配置详解具体的方法路由器接入ADSL配置详解1、Cisco路由器连接ADSL modem的PPPoE配置：说明:此案例为北京电信adsl PPPoE接入,需要使用一个普通adsl modem和一台cisco 2500路由器(双以太口),IOS 12.2(15)T,能够实现局域网共享上网.此案例配置共分7步:第一步:配置vpdn vpdn e1、Cisco路由器连接ADSL modem的PPPoE配置：说明:此案例为北京电信adsl PPPoE接入,需要使用一个普通adsl modem和一台cisco 2500路由器(双以太口),IOS 12.2(15)T,能够实现局域网共享上网.此案例配置共分7步:第一步:配置vpdnvpdn enable(启用路由器的虚拟专用拨号网络---d)vpdn-group office(建立一个vpdn组,)request-dialin(初始化一个d 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 Ethernet1no ip addresspppoe enable允许以太接口运行pppoepppoe-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 Dialer1ip 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NATencapsulation 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 10.1.1.1 255.255.255.0ip 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 10.1.1.1ip dhcp pool ABCimport all(导入dns和wins server)network 10.1.1.0 255.255.255.0default-router 10.1.1.1第六步:配置NAT:access-list 1 permit 10.1.1.0 0.0.0.255cc第七步:配置缺省路由ip route 0.0.0.0 0.0.0.0
