Cisco adsl configuration instructions (interface ATM0)

This article describes how to configure ADSL with specific operation examples. I believe that you will learn the detailed configuration process through the following configuration. You also have some knowledge about configuration commands.

!

Vpdn enable

No vpdn logging

<= Because the PPPoE application of ADSL is implemented through virtual dialing, VPDN must be used in the router.

!

Vpdn-group pppoe <= started the vpdn process for PPPoE

Request-dialin

Protocol pppoe <= set the dialing protocol to PPPoE

!

Interface FastEthernet0 <= set the company's internal network address

Ip address 192.168.0.1 255.255.255.0

Ip nat inside <= Enable NAT translation and set the Fast ethernet port to the internal network,

Convert the original address of the data received from the internal network to the Public Address

!

Interface ATM0 <= set the ADSL Port

No ip address <= do not set the address

No atm ilmi-keepalive

Dsl operating-mode auto

Hold-queue 224 in

Interface ATM 0.1 point-to-point

Dialer-pool 1 is referenced here.

!

Interface Dialer1

<= Create a virtual dialing Port

Ip address negotiated

<= Because dynamic addresses are provided by the local terminal, you must set the address to be obtained through negotiation.

Ip mtu 1492 <= Modify mtu value to apply to ADSL Network

Ip nat outside <= Enable NAT translation. Set this port to an external network.

Encapsulation ppp <= use the PPP frame format

Dialer pool 1

Ppp authentication pap callin <= sets the dialing verification method to pap.

Ppp pap sent vip pass vip <= user name and password for sending

Ip nat inside source list 1 interface Dialer1 overload

Ip classless

Ip route 0.0.0.0 0.0.0.0 dialer1

<= Forward all unroutable data packets to the ADSL line and set the default route

No ip http server
