Broadband Subscriber Management DHCPv4 Layer 3 Wholesale Topology and Configuration Elements

The network topology for the subscriber management DHCPv4 Layer 3 wholesale solution includes configuring separate routing instances for individual retailers that use a portion of the router. This solution uses a DHCPv4 relay configuration. However, you can also implement DHCPv4 Relay Proxy or DHCPv4 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.

Retailers have MSANs linking to MX Series router in wholesaler space. Wholesaler and retailers use RADIUS and DHCP servers for authentication and IP management.

A DHCP Layer 3 wholesale network solution can use various combinations of the following configuration elements:

Subscriber network VLAN configuration
DHCPv4 configuration (DHCPv4 Relay, DHCPv4 Relay Proxy, or DHCPv4 Local Server)
Addressing server or addressing server access configuration (if not using DHCPv4 Local Server)
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
