Introduction

The following information provides examples for configuring traffic accounting.

Prerequisites

The following information applies to Comware 9-based routers. Procedures and information in the examples might be slightly different depending on the software or hardware version of the MSR routers.

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 traffic accounting.

Example: Configuring traffic accounting

Network configuration

As shown in Figure 1, configure the routers as follows:

·     Configure LDP to establish LSPs between Router A and Router C, so subnets 11.1.1.0/24 and 21.1.1.0/24 can reach each other over MPLS.

·     Configure LDP to establish LSPs only for destinations 1.1.1.9/32, 2.2.2.9/32, 3.3.3.9/32, 11.1.1.0/24, and 21.1.1.0/24 on Router A, Router B, and Router C. Configure the penultimate hop not to pop the label on Router B.

·     On Router A, Router B, and Router C, configure traffic accounting for traffic from subnet 11.1.1.0/24 to subnet 21.1.1.0/24 to identify links that have packet loss.

Software versions used

This configuration example was created and verified on Release 9141P16 of the MSR2630E-X1 router.

Procedures
