Broadband Subscriber Management PPPoE Layer 3 Wholesale Topology and Configuration Elements

The network topology for the subscriber management PPPoE Layer 3 wholesale solution includes configuring separate routing instances for individual retailers that use a portion of the router.

To explain the concept, but to limit complexity, this solution provides a configuration with one wholesaler and only two retailers. Figure 1 illustrates a basic PPPoE Layer 3 wholesale topology model from which you can expand.

When you are configuring a PPPoE Layer 3 wholesale network solution, the following configuration elements are required:

• Subscriber network VLAN configuration

• Addressing server or addressing server access configuration

• RADIUS server access configuration

• Dynamic profile configuration for default (wholesaler) access

• Routing instance configuration for individual retailers

• Group configuration and forwarding options for the network

• Core network configuration

This implementation of PPPoE Layer 3 wholesale supports the following:

• Dynamic PPPoE interface creation.

• Static VLAN use only.

• AAA server assignment of subscribers to different routing instances within the same (default) logical system only.
