Broadband Subscriber Management DHCP Layer 3 Wholesale Topology and Configuration Elements
The network topology for the subscriber management DHCP Layer 3 wholesale solution includes configuring separate routing instances for individual retailers that use a portion of the router. This solution uses a DHCP relay configuration. However, you can also implement DHCP Relay Proxy or DHCP Local Server configuration.
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 Layer 3 wholesale topology model from which you can expand.

When you are configuring a DHCP Layer 3 wholesale network solution, the following configuration elements are required:
- Subscriber network VLAN configuration
- DHCP configuration
- Addressing server or addressing server access configuration
- RADIUS server access configuration
- Dynamic profile configuration for default (wholesaler) access
- Dynamic profile configuration for retailer access (following subscriber redirection; if applicable)
- Routing instance configuration for individual retailers
- Group configuration and forwarding options for the network
- Core network configuration
