PPPoE configuration process display

For the PPPoE configuration content, let's analyze a case. Let's take a look at the network topology of PPPoE configuration. From the topology below, let's take a look at the specific network environment. Then parse the configuration process.

The configuration of this case is divided into seven steps:

PPPoE configuration Step 1: Configure vpdn

Vpdn enable (vpdn)

Vpdn-group office (create a vpdn group ,)

Request-dialin (initialize a vpnd tunnel and create a vpdn sub-group to which the request is dial ,)

Protocol pppoe (vpdn sub-group uses pppoe to establish a session tunnel)

Step 2 of PPPoE configuration: configure the interface for connecting the router to the adsl modem

Interface Ethernet1

Pppoe enable allows the Ethernet interface to run pppoe

Pppoe-client dial-pool-number 1 Add the pppoe dialing client of the Ethernet interface to the dialing pool 1

Step 3 of PPPoE configuration: configure the logical dialing Interface

Interface Dialer1

Ip address negotiated obtains the ip address from the dynamic negotiation of the adsl service provider

Ip nat outside enables NAT for this interface

Encapsulation ppp encapsulates the ppp protocol for this interface

Dialer pool 1 this interface uses the dial-up pool No. 1 for dialing

Dialer-group 1 this command is of little significance to pppoe

Ppp authentication pap callin enables ppp pap Verification

Ppp pap sent-username account name and password

Step 4 of PPPoE configuration: Configure internal network interfaces

Interface Ethernet0 (internal network interface)

Ip address 10.1.1.1 255.255.255.0

Ip nat inside enables NAT for this interface

Step 5 of PPPoE configuration: configure the router to provide dhcp service for internal network hosts

Ip dhcp excluded-address 10.1.1.1

Ip dhcp pool ABC

Import all (import dns and wins server)

Network 10.1.1.0 255.255.255.0

Default-router 10.1.1.1

Step 6 of PPPoE configuration: Configure NAT

Access-list 1 permit 10.1.1.0 0.0.255

Ip nat inside source list 1 interface Dialer1 overload

Step 7 of PPPoE configuration: configure the default route

Ip route 0.0.0.0 0.0.0.0 Dialer1

PPPoE configuration requires chap authentication in some regions. The corresponding commands are as follows:

Ppp authentication chap callin

Ppp chap hostname abc123 @ baidu

Ppp chap password **********
