PBB Features

PBB OAM

Alcatel-Lucent's PBB implementation support both MPLS and native Ethernet tunneling. In the
case of an MPLS, SDP bindings are used as the B-VPLS infrastructure while T-LDP is used for
signaling. As a result, the existing VPLS, MPLS diagnostic tools are supported in both I-VPLS
and B-VPLS domains as depicted in

When an Ethernet switching backbone is used for aggregation between PBB PEs, a SAP is used as
the B-VPLS uplink instead of an SDP. No T-LDP signalling is available.
The existing IEEE 802.1ag implemented for regular VPLS SAPs may be used to troubleshoot
connectivity at I-VPLS and B-VPLS layers.
