3. © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 3 Consolidation Consolidate along the following areas: 1.PBB-VPLS PE model and network architecture 2.Interoperability scenarios among MPLS, PBBN, and PBN access networks 3.MAC Flushing Mechanisms 4.Multicast Pruning for PBB-VPLS

4. © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 4 PBB-VPLS PE Model and Network Architecture  Describe possible PE models with PBB components similar to previously defined PE models for PB components Both I & B components Only B component  Describe PE processing for MPLS, PBBN, and PBN access networks  Describe possible mapping of customer service instances to a VPLS instance

5. © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 5 Interoperability Scenarios & Use Cases  Describe possible interoperability scenarios and use cases: Interop with PBBN access network Interop with PBN access network Interop with MPLS access network Migration/hybrid scenarios

6. © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 6 MAC Flushing Mechanisms  Describe MAC flushing mechanisms based on In-band signaling (Native) Out-of-band signaling (LDP)  If consensus cannot be reached, then each mechanism may be progressed separately.

All rights reserved.Cisco ConfidentialPresentation_ID 7 Multicast Pruning for PBB-VPLS  Describe auto-discovery mechanism based on BGP for B-MAC group addresses and how these discovered info is used for mcast pruning over VPLS network  Have a short paragraph to describe mcast pruning may also be performed using MMRP along with applicability and scaling constrains
