Cisco ATM lab configuration

This document provides step-by-step instructions for setting up an ATM switched virtual circuit (SVC) using Cisco static mapping. This configuration will allow the router of one end to ping the router of the other end over an ATM Virtual Circuit.

Requirements

· (2) console cables

· PC with serial connection

· (3) bidirectional multi-mode fiber cables

· (2) Cisco 7200 routers (with ATM module installed)

· (2) Cisco LightStream 1010 switches (with ATM module installed)

***NOTE: THE PING SUCCESS RATE IS ONLY 80% THE FIRST TIME. THIS IS DUE TO THE INITIAL SETUP OF THE LINK.

Verify

A layer 3 connection now exists between 7200A and 7200B. You should be able to ping 10.1.1.2 from 7200A and be able to ping 10.1.1.1 from 7200B.
