PBB Features

Integrated PBB-VPLS Solution

HVPLS introduced a service-aware device in a central core location in order to provide efficient
replication and controlled interaction at domain boundaries. The core network facing provider
edge (N-PE) devices have knowledge of all VPLS services and customer MAC addresses for local
and related remote regions resulting in potential scalability issues as depicted in
U-PE
In a large VPLS deployment, it is important to improve the stability of the overall solution and to
speed up service delivery. These goals are achieved by reducing the load on the N-PEs and
respectively minimizing the number of provisioning touches on the N-PEs.
The integrated PBB-VPLS model introduces an additional PBB hierarchy in the VPLS network to
address these goals as depicted in
