Broadband Subscriber Management DHCPv6 Layer 3 Wholesale Topology and Configuration Elements
The network topology for the subscriber management DHCPv6 Layer 3 wholesale solution includes configuring separate routing instances for individual retailers that use a portion of the router. This solution uses a DHCPv6 local server configuration.
 | Note: Only DHCPv6 local server is currently supported for DHCPv6 Layer 3 wholesale 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.
Figure 1: Basic Subscriber Management DHCPv6 Layer 3 Wholesale Solution Topology
A DHCPv6 Layer 3 wholesale network solution can use various combinations of the following configuration elements:
- Subscriber network VLAN configuration
- DHCPv6 configuration (local server only)
- 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
