Wholesale Network Configuration Options and Considerations

You can configure a wholesale network any number of ways using Juniper Networks hardware and Junos OS software. The general configuration options, and considerations for each, are provided in the following table:

Wholesale Configuration Options

Considerations

Fully Static (all interfaces, VLANs, and routing instances are configured statically)

Providing more control over retailer space and access, this option is more labor intensive and can require more detailed planning of the network, address allocation, and so on.

Static VLANs and Dynamic Demux Interfaces

Service VLANS are created statically and must be managed. Demux interfaces are dynamically created over the service VLANs. This option uses more logical interfaces; one for each VLAN and one for each dynamic demux interface that runs over each VLAN.

Dynamic VLANs Only (dedicated customer VLANs for each subscriber)

Dynamic (auto-sensed) VLANs are authenticated and installed in the correct non-default routing instance before DHCP is instantiated. This method helps to conserve logical interfaces by avoiding the need for additional logical interfaces being created for each demux interface.

Note:

In a customer VLAN model, each VLAN functions on a 1:1 basis for each customer (in this case, per household).

Dynamic VLANs and Dynamic Demux Interfaces

Allows for the greatest ease of use and flexibility in configuring subscribers, by enabling access over a service VLAN and targetting more service levels over individual, dynamically-created demux interfaces over the service VLAN. This option uses more logical interfaces; one for each VLAN and one for each demux interface that runs over each VLAN.
