Introduction

This document provides PPP configuration examples.

Prerequisites

This document applies to Comware V7-based MSR routers. Procedures and information in the examples might be slightly different depending on the software or hardware version of the router.

The configuration examples in this document 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.

This document assumes that you have basic knowledge of PPP, MP, and PPPoE.

Example: Configuring MP and CHAP

Network requirements

As shown in Figure 1, bind Serial 2/0 and Serial 2/1 into an MP bundle on an MP-group interface. Specify CHAP as the authentication mode for each PPP link.

Figure 1 Network diagram

 

Software version used

This configuration example was created and verified on R0106.

Configuration restrictions and guidelines

When you configure MP and CHAP, follow these restrictions and guidelines:

·     The username and password on each end must be the same for CHAP authentication.

·     To bring up the configured serial interfaces, use the shutdown and then undo shutdown commands.

·     Make sure you create a network access user.

Configuration procedures

Configuring Device A

# Create a user account for Device B.
