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 orthe
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 andpassword you
want to use.
For more information about SDM please follow the instructions in the
QUICK START
GUIDE for your router or go to http://www.cisco.com/go/sdm

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---***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 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
