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.
Figure 1: Basic Subscriber Management PPPoE Layer 3 Wholesale Solution Topology
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.
