PBB Features
The solution described in this section limits the scope of MMRP control plane advertisements to a
specific network domain using MRP Policy. ISID-based filters are also provided as a safety
measure for BVPLS data plane.

(MANs) are interconnected through a wide area network (WAN). A BVPLS is configured across
these domains running PBB M:1 model to provide infrastructure for multiple IVPLS services.
MMRP is enabled in the BVPLS to build per IVPLS flooding trees. In order to limit the load in the
core PEs or PBB BCBs, the local IVPLS instances must use MMRP and data plane resources only
in the MAN regions where they have sites. A solution to the above requirements is depicted in
Figure
this example. Other technology combinations are possible.
