Cisco路由器连接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

!

www.2cto.com

!--- 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.

www.2cto.com

!

!--- 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

ppp chap 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

!--- ppp chap password

!--- with the following two lines:

!--- ppp authentication pap callin

!--- ppp pap sent-username password

www.2cto.com

!--- For NAT we are going to overload on the Dialer1

!--- interface and add a default route out

!--- since dialer ip address can change.
