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.
