Introduction

This document provides PBB configuration examples.

Prerequisites

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 PBB.

Example: Configuring PBB

Network configuration

As shown in Figure 1, Site A and Site B both have VLANs 100 through 120.

•

Configure QinQ on Device Aand Device B to transmit VLANs 100 through 120 in SVLAN 1000.

•

Configure PBB on BEB 1 and BEB 2 to extend the VLANs across the two sites.

Figure 1 Network diagram

Analysis

To meet the network requirements, you must perform the following tasks on BEB 1 and BEB 2:

•

Configure a service instance on the downlink port to match frames that have an outer VLAN ID

of 1000.

•

Specify the access mode and data encapsulation type of the PBB VSI as Ethernet to retain the

VLAN tags of the customer frames.
