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.

Software versions used

This configuration example was created and verified on S6860-CMW710-R2612.

Restrictions and guidelines

You need to configure PBB only on BEBs.

Procedures

Configuring BEB 1

# Create VLAN 1000 and VLAN 2000.

<BEB1> system-view

[BEB1] vlan 1000

[BEB1-vlan1000] quit

# Enable L2VPN.

[BEB1] l2vpn enable

# Create a VSI.

[BEB1] vsi test

# Assign PBB I-SID 1 to the VSI.

[BEB1-vsi-test] pbb i-sid 1

# Specify B-VLAN 2000 for the PBB VSI.

# Configure Ten-GigabitEthernet 1/0/1 as a trunk port, assign it to VLAN 2000, and remove it from VLAN 1. Configure Ten-GigabitEthernet 1/0/1 as an uplink port of the PBB VSI.

[BEB1] interface ten-gigabitethernet 1/0/1

[BEB1-Ten-GigabitEthernet1/0/2] port trunk permit vlan 1000

[BEB1-Ten-GigabitEthernet1/0/2] undo port trunk permit vlan 1

# Create service instance 1 on Ten-GigabitEthernet 1/0/2.

[BEB1-Ten-GigabitEthernet1/0/2] service-instance 1

# Configure the service instance to match frames that have an outer VLAN ID of 1000. Associate the service instance with the PBB VSI, and set the access mode to Ethernet.

[BEB1-Ten-GigabitEthernet1/0/2-srv1] encapsulation s-vid 1000

[BEB1-Ten-GigabitEthernet1/0/2-srv1] xconnect vsi test access-mode ethernet

# Enable Ethernet encapsulation for the PBB VSI.

[BEB1] vsi test

[BEB1-vsi-test] pbb i-sid 1

[BEB1-vsi-test-1] encapsulation ethernet

[BEB1-vsi-test-1] quit

[BEB1-vsi-test] quit

Configuring BEB 2

# Configure BEB 2 in the same way BEB 1 is configured. (Details not shown.)

Configuring BCB

# Create VLAN 2000.

<BCB> system-view

[BCB] vlan 2000

[BCB-vlan2000] quit

# Configure Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 as trunk ports, assign them to VLAN 2000, and remove them from VLAN 1.

[BCB] interface range ten-gigabitethernet 1/0/1 to ten-gigabitethernet 1/0/2

[BCB-if-range] port link-type trunk

[BCB-if-range] port trunk permit vlan 2000

[BCB-if-range] undo port trunk permit vlan 1

[BCB-if-range] quit

Configuring Device A

# Create VLAN 1000.

<DeviceA> system-view

[DeviceA] vlan 1000

[DeviceA-vlan1000] quit

# Configure Ten-GigabitEthernet 1/0/1 as an access port, and assign it to VLAN 1000.

[DeviceA] interface ten-gigabitethernet 1/0/1

[DeviceA-Ten-GigabitEthernet1/0/1] port access vlan 1000

# Enable QinQ on Ten-GigabitEthernet 1/0/1.

[DeviceA-Ten-GigabitEthernet1/0/1] qinq enable

[DeviceA-Ten-GigabitEthernet1/0/1] quit

# Configure Ten-GigabitEthernet 1/0/2 as a trunk port, assign it to VLAN 1000, and remove it from VLAN 1.
