Configuring PBB

Overview

IEEE 802.1ah Provider Backbone Bridge (PBB) is a MAC-in-MAC Layer 2 VPN technology. It
interconnects multiple provider bridged networks to build a large scale end-to-end Layer 2 provider
bridged network.

PBB network model

As shown in
edge bridges and backbone core bridges.
Backbone edge bridges connect customer sites or provider bridge networks to the PBB network. They
encapsulate the customer MAC in the service provider MAC. The backbone core bridges forward traffic
based on the service provider MAC.

Terminology

PBBN
A network using PBB is a provider backbone bridge network (PBBN). A PBBN is a Layer 2 switching
network where Layer 2 connections are established between different nodes.
