WAN

Configuration

Guide

This chapter provides an overview of Wide Area Network (WAN) applications as well as an overview of both Frame Relay and PPP configuration for the SSR. In addition, you can view an example of a multi-router WAN configuration complete with diagram and configuration files in “WAN Configuration Examples” on page 350.

WAN Overview

On the SmartSwitch Router, Wide Area Network (WAN) routing is performed over a serial interface using two basic protocols: Frame Relay and point-to-point protocol (PPP). Both protocols have their own set of configuration and monitoring CLI commands described in the SmartSwitch Router Command Line Interface Reference Manual.

High-Speed Serial Interface (HSSI) and Standard Serial Interfaces

In both the Frame Relay and PPP environments on the SSR, you can specify ports to be High-Speed Serial Interface (HSSI) or standard serial interface ports, depending, of course, on the type of hardware you have. Each type of interface plays a part in the nomenclature of port identification. You must use either the “hs.” or “se.” prefix for HSSI and serial interfaces, respectively, when specifying WAN port identities.

For example, you would specify a frame relay serial WAN port located at router slot 4, port 1, on VC 100 as “se.4.1.100”.
