MPLS L2VPN

MPLS L2VPN

The S9300&S9300E have powerful MPLS VPN capability.

As shown in Figure 3-9 and Figure 3-10, the S9300&S9300E function as the UPE on a L2VPN network, supporting VLL and VPLS and providing point-to-point and multipoint-to-multipoint VPN services.

As shown in Figure 3-11, by cooperating with the DSLAM, Access Gateway (AG), and Layer 2 switches, the S9300&S9300E map access services to VLL or VPLS services.

  • Along with the DSLAM/AG, the S9300&S9300E map QinQ tunnels to VLL or VPLS service instances, facilitating Digital Subscriber Line (DSL)-based VLL services.

  • Along with Layer 2 switches, the S9300&S9300E map QinQ tunnels and VLL tunnels to VLL or VPLS service instances.

The S9300&S9300E handle multiple services at both the access and aggregation layers. The S9300&S9300E can map specific personal services such as broadband access and VoIP to VLL or VPLS service instances.

The S9300&S9300E provide low-cost VLL or VPLS solutions, allowing MPLS and MPLS VPN to be applied at the edge aggregation layer.

  • Solves the issue of pure Ethernet with respect to scalability, carrier-class reliability, and manageability.

  • Lessens the burden on higher-level NPEs and eliminates single-site faults.

  • Customizes services through distributed service processing using services implemented by devices at the edge aggregation layer.
