Network Access Configuration Overview

The Junos operating system (Junos OS) enables you to configure network access features for the device at the [edit access] hierarchy level. This includes Layer 2 Tunneling Protocol (L2TP), Point-to-Point Protocol (PPP), and Subscriber Access configuration.

The PPP is an encapsulation protocol for transporting IP traffic across point-to-point links. The L2TP protocol allows PPP to be tunneled within a network. For M7i, M10i, and M120 routers, you can configure L2TP tunneling security services on an Adaptive Services or a MultiServices Physical Interface Card (PIC).

For information about configuring Subscriber Access, see Broadband Subscriber Sessions User Guide. For information about multilink PPP (MLPPP), see Link and Multilink Services Interfaces User Guide for Routing Devices.
