About This Guide

Use this guide to understand how to configure the primary methods for accessing the subscriber network:

  • DHCP provides IP address configuration and service provisioning.

  • PPP enables a point-to-point direct connection to the network and service provider. Dynamic profiles apply configurations and services to authenticated subscribers.

  • L2TP separates the termination of access technologies from the termination of PPP and subsequent access to a network. This separation enables service providers to outsource their access technologies. L2TP provides ISPs the capability to supply VPN service; private enterprises can reduce or avoid investment in access technologies for remote workers.

  • MPLS pseudowire interfaces extend MPLS domains from the access-aggregation network to the service edge.

  • Wi-Fi access gateways provide public Wi-Fi access from residential or business Wi-Fi networks so that mobile subscribers can be authenticated and connected regardless of their physical location.

  • Fixed wireless access enables service providers to manage subscribers over a wireless network to the home instead of having to run fiber to the building. The wireless network reduces last-mile installation and maintenance costs and gives providers the ability to increase services to underserved end users.
