Introduction

This document provides examples for configuring PPPoE on routers.

Prerequisites

This document is not restricted to specific software or hardware versions. Procedures and information in the examples might be slightly different depending on the software or hardware version of the device.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of PPPoE.

Software versions used

This configuration example was created and verified on Version 7.1.064 Feature 6749L15 of the MSR3610 router.

Configuration example

Network configuration

As shown in Figure 1, a company requires external office staff to access the internal network through PPPoE. The ISP provides a PPPoE account with the username as vpdnuser and the password as user1234, along with DNS addresses 5.5.5.5 and 6.6.6.6.

Figure 1 Network diagram

 

Analysis

1.     Configure an address pool for allocating IP addresses to hosts.

2.     Host accesses the company's internal server through PPPoE.

Procedures

Configuring the router

Configuring IP addresses for interfaces

# Enter the view of interface GigabitEthernet 0/1 and configure its IP address as 20.1.1.1/24.

<Router> system-view

[Router] interface gigabitethernet 0/1

[Router-GigabitEthernet0/1] ip address 20.1.1.1 24

[Router-GigabitEthernet0/1] quit

# Enter the view of interface GigabitEthernet 0/2 and configure its IP address as 192.168.2.1/24.

[Router] interface gigabitethernet 0/2

[Router-GigabitEthernet0/2] ip address 192.168.2.1 24

[Router-GigabitEthernet0/2] quit

Configuring a dialer interface

# Configure dialer group 1 to dial through DDR for IP packets.

[Router] dialer-group 1 rule ip permit

# Create dialer interface 1.

[Router] interface dialer 1

# Enable bundle DDR.

[Router-Dialer1] dialer bundle enable

# Create dialer group 1.

[Router-Dialer1] dialer-group 1

# Enable IP address negotiation on the interface, so that the interface can accept the IP address allocated by the server.

[Router-Dialer1] ip address ppp-negotiate

# Configure the PPPoE session to operate in permanent mode.

[Router-Dialer1] dialer timer idle 0

# Configure the account used for dialup.

[Router-Dialer1] ppp chap user vpdnuser

# Configure the password used for dialup.

[Router-Dialer1] ppp chap password simple user1234

# Configure the interface to accept the DNS server IP addresses assigned by the peer even though it does not request DNS server IP addresses from the peer.

[Router-Dialer1] ppp ipcp dns admit-any

# Enable the interface to actively request the DNS server IP address from its peer.

[Router-Dialer1] ppp ipcp dns request

# Configure NAT.

[Router-Dialer1] nat outbound

[Router-Dialer1] quit

# Bind the dialer interface to physical interface GigabitEthernet 0/1.

[Router] interface GigabitEthernet 0/1

[Router-GigabitEthernet0/1] pppoe-client dial-bundle-number 1

[Router-GigabitEthernet0/1] quit

Configuring the default route

# Configure the default route to the Internet.

[Router] ip route-static 0.0.0.0 0 Dialer 1

Configuring address pools

# Enable DHCP.

[Router] dhcp enable

# Create address pool pool1 for address allocation.

[Router] dhcp server ip-pool pool1

# Specify the subnets for address allocation.

[Router-dhcp-pool-pool1] network 192.168.2.0 mask 255.255.255.0

[Router-dhcp-pool-pool1] address range 192.168.2.2 192.168.2.254

# Configure the gateway for the address pool.

[Router-dhcp-pool-pool1] gateway-list 192.168.2.1

# Configure a DNS server address.

[Router-dhcp-pool-pool1] dns-list 5.5.5.5 6.6.6.6

[Router-dhcp-pool-pool1] quit

Configuring the PPPoE client

NOTE: On Host, configure the PPPoE client. In this example, the PC is installed with Windows 7.

 

# Log in to Host. Click the Network  icon in the lower right corner of the PC, and click Open Network and Sharing Center.

Figure 2 Opening the network and sharing center window

 

# Click Set up a new connection or network to create an L2TP client.

Figure 3 Setting up a new connection or network

 

# In the Set up a Connection or Network window, select Connect to a workplace, and then click Next.

Figure 4 Connecting to the Internet

 

# Select the Broadband (PPPoE) option to begin configuring the connection method.

Figure 5 Using broadband (PPPoE)

 

# In the User name and Password fields, enter the username and password set on the PPPoE server, vpdnuser and user1234 in this example. Configure the connection name as PPPoE. Click Create.

Figure 6 Entering the configuration

 

# Click Connect to complete the configuration.

Verifying the configuration

After successfully establishing the PPPoE connection, verify that Host can ping the internal network server (FTP server).
