Alcatel-Lucent implementation provides a solution for both PBB ELINE (EPIPE) and ELAN

(IVPLS) services that avoids PBB blackholing when the active ES11-BEB1 link fails. It also

provides a consistent behavior for both service type and for different backbone types: for example,

native Ethernet, MPLS, or a combination. Only MC-LAG is supported initially as the Access-

Multi-homing mechanism.

Solution Description for I-VPLS Over Native PBB Core

The use case described in the previous section is addressed by enhancing the existing native PBB

solution to provide for blackhole avoidance.

The topology depicted in

Although the native PBB use case is used, the solution works the same for any other PBB

infrastructure: for example, G.8031 Ethernet tunnels, pseudowire/MPLS, or a combination.
