AR720 ROUTER QUICK START GUIDE 17

Configuring an IP Network

Protocol (PPP) over a wide area link. Each router is attached to

an Ethernet LAN on which there is a mixture of PCs and hosts.

BEFORE YOU START

1 Ensure that the routers to be configured are connected to

the Ethernet LAN and the wide area link, and that the link is

operational. See Getting Connected for information about

connecting the router to a physical network.

2 Connect a terminal to the console port (port 0) on each

router, as described in the AR700 Series Router Quick Install

Guide. Alternatively, you can connect a PC to the console port

TCP/IP is the most widely used network protocol. The Internet

uses TCP/IP for routing all its traffic. TCP/IP provides a range of

services including remote login, Telnet, file transfer (FTP), Email

and access to the World-Wide Web.

The AR720 router routes TCP/IP across the wide area network

using services like ISDN, Frame Relay and leased lines, enabling

remote TCP/IP LANs to be joined together as a single internet

to exchange information.

This example illustrates the steps required to configure TCP/IP

using the router’s command line interface. Two routers running

TCP/IP will be connected together using the Point-to-Point
