CISCO ADSL 配置说明
－－－－－－－－－－－－－－－－－－－－－－－－－－
!
vpdn enable
no vpdn logging
<=由于ADSL的PPPoE应用是通过虚拟拨号来实现的所以在路由器中需要使用VPDN的功能
!
vpdn-group pppoe <=为PPPoE启动了VPDN的进程
request-dialin
protocol pppoe <=设置拨号协议为PPPoE
!
interface FastEthernet0 <=设置公司内部网络地址
ip address 192.168.0.1 255.255.255.0
ip nat inside <=为启用NAT转换，设置Fast ethernet端口为内部网络，
从内部网络收到的数据的原地址转换为公网地址
!
interface ATM0 <=设置ADSL端口
no ip address <=请不要设置地址
no atm ilmi-keepalive
bundle-enable
dsl operating-mode auto
hold-queue 224 in
interface ATM0.1 point-to-point
<=ADSL的通讯 依靠VC，所以必须设定点到点VC
pvc 8/35 <=设置PVC的相关参数， 即VCI和VPI的值，
如果不清楚请向局端查询
pppoe-client dial-pool-number 1
<=PPPoE拨号进程使用了常规的拨号进程，
这里引用了dialer-pool 1
!
interface Dialer1
<=建立一个虚拟拨号端口
ip address negotiated
<=由于局端提供动态地址，所以必须设定地址为协商获得
ip mtu 1492 <=修改mtu值以适用于ADSL网络
ip nat outside <=为启用NAT转换，设置该端口为外部网络
encapsulation ppp <=使用PPP的帧格式
dialer pool 1
ppp authentication pap callin <=设置拨号的验证方式为pap
ppp pap sent vip pass vip <=发送用户名和密码
ip nat inside source list 1 interface Dialer1 overload
<=设置了NAT的转换方式，使用了dialer 1端口的动态地址
ip classless
ip route 0.0.0.0 0.0.0.0 dialer1
<=将所有不可路由的数据报转发给ADSL线路，设定缺省路由
no ip http server
!
Access-list 1 permit 10.92.1.0 0.0.0.255

2600接adsl的两种方式
--------------------------------------------------------------------------------
一.WIC-ADSL 卡接线路
vpdn enable
no vpdn logging
!
vpdn-group pppoe
request-dialin
protocol pppoe
!
inter f0/0
ip add 192.168.0.1 255.255.255.0
ip nat inside
ip tcp adjust-mss 1450
!
inter ATM0
no ip address
no atm ilmi-keepalive
bundle-enable
dsl operating-mode auto
hold-queue 224 in
interface ATM0.1 POINT-TO-POINT
pvc 8/35 此处的pvc值8/35要根据具体情况而定，咨询电信
pppoe-client dial-pool-number 1
!
inter dialer1
ip address negotiated
ip nat outside
encap ppp
dialer pool 1
ppp authen pap callin
ppp pap sent xxxx pass xxxx 用户名密码
!
ip nat inside source list 1 interface dialer1 overload
ip calssess
ip route 0.0.0.0 0.0.0.0 dialer1
no ip http server
!
access-list 1 permit 192.168.0.0 0.0.0.255
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
二.或者利用另外一个以太网口 接到 ADSL MODEM再接线路
hostname xxxx
ip name-server x.x.x.x dns的地址
vpdn enable
vpdn-group pppoe
request-dialin
protocol pppoe
inter f 0/0
ip add 192.168.0.1 255.255.255.0
ip nat inside
inter f 0/1
no ip address
pppoe enable
pppoe-client dial-pool-number 1
inter dialer 1
mut 1492
ip address negotiated
ip nat outside
encap ppp
no ip mroute-cache
dialer pool 1
dialer-group 1
no cdp enable
ppp authen pap callin
ppp pap sent xxx pass xxx 用户名密码
ip nat inside source list 1 inter dialer 1 overload
ip classless
ip route 0.0.0.0 0.0.0.0 dialer1 permanent
no ip http server
ip pim bidir-enable
access-list 1 permit any
dialer-list 1 protocol ip permit
