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。

banner login ^C
-----------------------------------------------------------------------
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 <myuser> privilege 15 secret 0 <mypassword>
no username cisco
Replace <myuser> and <mypassword> with the username and password you
want to use.
For more information about SDM please follow the instructions in the
QUICK START
GUIDE for your router or go to

案例三
假设E0接内网，E1接ADSL上外网
{dy}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
