PBB Features

PBB ELINE Service

ELINE service is defined in PBB (IEEE 802.1ah) as a point-to-point service over the B-

component infrastructure. Alcatel-Lucent's implementation offers support for PBB ELINE

through the mapping of multiple Epipe services to a Backbone VPLS infrastructure.

The use of Epipe scales the ELINE services as no MAC switching, learning or replication is

required in order to deliver the point-to-point service.

All packets ingressing the customer SAP are PBB encapsulated and unicasted through the B-

VPLS "tunnel" using the backbone destination MAC of the remote PBB PE.

All the packets ingressing the B-VPLS destined for the Epipe are PBB de-encapsulated and

forwarded to the customer SAP.

The PBB epipe service can be protected using G.8032 (the G8032 instance is created to protect the

PBB B-VPLS service). For more information and for an example see

The following VPLS resiliency mechanisms are also supported in PBB VPLS:

Native Ethernet resiliency supported in both I-VPLS and B-VPLS contexts

Distributed LAG, MC-LAG, RSTP

MSTP in a management VPLS monitoring (B- or I-) SAPs.

The G.8032 is supported for B-VPLS service. The G.8032 support is used only with PBB

Epipe service from the current releases and cannot be used with PBB I-VPLS service.
