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 A and 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.

Applicable hardware and software versions

The following matrix shows the hardware and software versions to which this configuration example is applicable:

 

Hardware	Software version
S6800 switch series S6860 switch series	Release 2702
S6861 switch series	Not supported

 

Restrictions and guidelines

You need to configure PBB only on BEBs.
