Cisco routing OSPF over ATM configuration

In part 1 of this project we set up an ATM VC and we were able to ping from one router to the other. Now we will set up OSPF routing so that we can share routes between the 2 7200 routers over the ATM link.

This document provides step-by-step instructions for setting up OSPF to connect over an ATM VC

Prerequisites

See Part 1 Configure the ATM Switched Virtual Circuit (SVC)

Procedure

1. Complete all tasks in Configure the ATM Switched Virtual Circuit (SVC)

1. Power on devices

1. Connect to Cisco 7200A via console cable

7200A#

conf t

interface fa2/0

ip address 10.10.1.1 255.255.255.0

no shut

!

router ospf 1

network 10.0.0.0 0.255.255.255 area 0

neighbor 10.1.1.2

*NOTE THE NEIGHBOR COMMAND MUST BE DONE MANUALLY FOR 7200A TO BE ABLE TO FIND AND ROUTE TO 7200B.

7200B#

conf t

interface fa2/0

ip address 10.20.1.1 255.255.255.0

no shut

!

router ospf 1

network 10.0.0.0 0.255.255.255 area 0

neighbor 10.1.1.1

Verify

Both routers should now list remote routes. This can be verified using the “show ip route” command. You should be able to ping 10.20.1.2 from 10.10.1.2, and be able to ping 10.10.1.2 from 10.20.1.2.
