Broadband Subscriber Management Layer 2 Wholesale Topology and Configuration Elements

The network topology for the subscriber management Layer 2 wholesale solution includes configuring separate routing instances for individual retailers that use a portion of the router. This solution uses a Virtual Private LAN Service (VPLS) configuration.

Layer 2 wholesale networks are supported on MPC/MIC interfaces.

To explain the concept but limit complexity, this solution provides a configuration with one wholesaler and only two retailers. Figure 1 illustrates a basic Layer 2 wholesale topology model from which you can expand.

When you are configuring a Layer 2 wholesale network solution, the following configuration elements are required:

  • Subscriber access dynamic VLAN configuration including dynamic profile configuration for retailer routing instances

  • Routing instance configuration for individual retailers on provider edge (PE) routers and network-to-network interface (NNI) routers.

  • VLAN interface configuration

  • RADIUS server access configuration

  • Core network configuration
