Cisco路由器的ADSL modem配置詳解具體的方法
路由器接入ADSL配置詳解
1、Cisco路由器連接ADSL modem的PPPoE配置： 說明:此案例為北京電信adsl PPPoE接入,需要使用一個普通adsl modem和一臺cisco 2500路由器(雙以太口),IOS 12.2(15)T,能夠實現(xiàn)局域網共享上網.
此案例配置共分7步:
第一步:配置vpdn vpdn e
1、Cisco路由器連接ADSL modem的PPPoE配置：
說明:此案例為北京電信adsl PPPoE接入,需要使用一個普通adsl modem和一臺cisco 2500路由器(雙以太口),IOS 12.2(15)T,能夠實現(xiàn)局域網共享上網.
此案例配置共分7步:
第一步:配置vpdn
vpdn enable(啟用路由器的虛擬專用撥號網絡---d)
vpdn-group office(建立一個vpdn組,)
request-dialin(初始化一個d tunnel,建立一個請求撥入的vpdn子組,)
protocol pppoe(vpdn子組使用pppoe建立會話隧道)
第二步: 配置路由器連接adsl modem的接口
interface Ethernet1
no ip address
pppoe enable允許以太接口運行pppoe
pppoe-client dial-pool-number 1將以太接口的pppoe撥號客戶端加入撥號池1
第三步:配置邏輯撥號接口:
interface Dialer1
ip address negotiated從adsl服務商動態(tài)協(xié)商得到ip地址
ip nat outside為該接口啟用NAT
encapsulation ppp為該接口封裝ppp協(xié)議
dialer pool 1該接口使用1號撥號池進行撥號
dialer-group 1該命令對于pppoe是意義不大的
ppp authentication pap callin啟用ppp pap驗證
ppp pap sent-username xxxxxxx password 0 yyyyyyy使用已經申請的用戶名和口令
第四步:配置內部網絡接口
interface Ethernet0(內部網絡接口)
ip address 10.1.1.1 255.255.255.0
ip nat inside為該接口啟用NAT
第五步:配置路由器為內部網絡主機提供dhcp服務
ip dhcp excluded-address 10.1.1.1
ip dhcp pool ABC
import all(導入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
cc
第七步:配置缺省路由
ip route 0.0.0.0 0.0.0.0 Dialer1
2、Cisco路由器連接ADSL WIC卡之PPPoE配置解:
!
vpdn enable
no vpdn logging <=由于ADSL的PPPoE應用是通過虛擬撥號來實現(xiàn)的所以在路由器中需要使用VPDN的功能
!
vpdn-group pppoe <=為PPPoE啟動了VPDN的進程
request-dialin
protocol pppoe <=設置撥號協(xié)議為PPPoE
!
interface FastEthernet0 <=設置公司內部網絡地址
ip address 192.168.0.1 255.255.255.0
ip nat inside <=為啟用NAT轉換，設置Fast ethernet端口為內部網絡，從內部網絡收到的數(shù)據的原地址轉換為公網地址
!
interface ATM0/0 <=設置ADSL端口
no ip address <=請不要設置地址
no atm ilmi-keepalive
bundle-enable
dsl operating-mode auto
hold-queue 224 in
interface ATM0/0.1 point-to-point <=ADSL的通訊 依靠VC，所以必須設定點到點VC
pvc 8/81 <=設置PVC的相關參數(shù)， 即VCI和VPI的值，如果不清楚請向局端查詢
pppoe-client dial-pool-number 1 <=PPPoE撥號進程使用了常規(guī)的撥號進程，這里引用了dialer-pool 1
!
interface Dialer1 <=建立一個虛擬撥號端口 ip address negotiated <=由于局端提供動態(tài)地址，所以必須設定地址為協(xié)商獲得
ip mtu 1492 <=修改mtu值以適用于ADSL網絡
ip nat outside <=為啟用NAT轉換，設置該端口為外部網絡
encapsulation ppp <=使用PPP的幀格式
dialer pool 1
ppp authentication pap callin <=設置撥號的驗證方式為pap
ppp pap sent vip pass vip <=發(fā)送用戶名和密碼
ip nat inside source list 1 interface Dialer1 overload <=設置了NAT的轉換方式，使用了dialer 1端口的動態(tài)地址
!
ip classless
ip route 0.0.0.0 0.0.0.0 dialer1 <=將所有不可路由的數(shù)據報轉發(fā)給ADSL線路，設定缺省路由
no ip http server

access-list 1 permit 192.168.0.0 0.0.0.255

Cisco路由器連接ADSL WIC卡之PPPoE配置：
vpdn-group pppoe
request-dialin
!--- we are the PPPoE client requesting to establish
!--- a session with the aggregation unit (6400 NRP).
protocol pppoe
!
!--- internal Ethernet network.
!
interface FastEthernet0
ip address 10.92.1.182 255.255.255.0
ip nat inside
!--- DSL interface.
!
interface ATM0
no ip address
no atm ilmi-keepalive
bundle-enable
dsl operating-mode auto
hold-queue 224 in
!--- All defaults.
!--- PPPoE runs on top of AAL5SNAP, but the
!--- encap aal5snap command is not used.
!
interface ATM0.1 point-to-point
pvc 1/1
pppoe-client dial-pool-number 1
!--- pvc 1/1 is an example value that must be changed
!--- to match the value used by the ISP.
!
!--- The PPPoE client code ties into a dialer interface upon
!--- which a virtual-access interface is cloned.
!
interface Dialer1
ip address negotiated
ip mtu 1492
!--- Ethernet MTU default = 1500 (1492 + PPPoE headers = 1500)
ip nat outside
encapsulation ppp
dialer pool 1
!--- Ties to atm interface.
ppp authentication chap callin
ppp chap hostname <username>
ppp chap password <password>
!
!--- The ISP will instruct you regarding
!--- the type of authentication to use.
!--- To change from PPP CHAP to PPP PAP,
!--- replace the following three lines:
!--- ppp authentication chap callin
!--- ppp chap hostname <username>
!--- ppp chap password <password>
!--- with the following two lines:
!--- ppp authentication pap callin
!--- ppp pap sent-username <username> password <password>
!--- For NAT we are going to overload on the Dialer1
!--- interface and add a default route out
!--- since dialer ip address can change.
ip nat inside source list 1 interface Dialer1 overload
ip classless
ip route 0.0.0.0 0.0.0.0 dialer1
