Learning Objectives
To complete this lab:
•

Cable a network according to the topology diagram

•

Erase the startup configuration and reload a router to the default state

•

Perform basic configuration tasks on a router

•

Configure and activate interfaces

•

Configure Spanning Tree Protocol

•

Configure VTP servers and client

•

Configure VLANS on the switches

•

Configure RIP routing on all the routers

•

Configure OSPF routing on all routers

•

Configure EIGRP routing on all the routers

Scenario
In this lab, you will review basic routing and switching concepts. Try to do as much on your own as
possible. Refer back to previous material when you cannot proceed on your own.
Note: Configuring three separate routing protocols—RIP, OSPF, and EIGRP—to route the same network
is emphatically not a best practice. It should be considered a worst practice and is not something that
would be done in a production network. It is done here so that you can review the major routing protocols
before proceeding, and see a dramatic illustration of the concept of administrative distance.

Task 1: Prepare the Network
Step 1: Cable a network that is similar to the one in the topology diagram.
Step 2: Clear any existing configurations on the routers.

Task 2: Perform Basic Device Configurations.
Configure the R1, R2, and R3 routers and the S1, S2, S3 switches according to the following guidelines:
•

Configure the hostname.

•

Disable DNS lookup.

•

Configure an EXEC mode password.

How are the routing decisions different now that OSPF is running?

____________________________________________________________________________
____________________________________________________________________________
____________________________________________________________________________
Before OSPF was added, the routers would take the path with the fewest number of hops. For example,
R3 would use its Serial0/0/0 interface to reach subnet 192.168.20.0 because it is one hop away. After
OSPF is running, the path taken is determined by the fastest path. Using the earlier example, R3 uses
Fast Ethernet 0/0.13 to reach subnet 192.168.20.0.
Step 3: Verify that RIP is still running.

Task 11: Clean Up
Erase the configurations and reload the routers. Disconnect and store the cabling. For PC hosts that are
normally connected to other networks (such as the school LAN or to the Internet), reconnect the
appropriate cabling and restore the TCP/IP settings.

192.168.30.1

Learning Objectives
Upon completion of this lab, you will be able to:
•

Cable a network according to the topology diagram

•

Erase the startup configuration and reload a router to the default state

•

Perform basic configuration tasks on a router

•

Configure and activate interfaces

•

Configure OSPF routing on all routers

•

Configure PPP encapsulation on all serial interfaces

•

Learn about the debug ppp negotiation and debug ppp packet commands

•

Learn how to change the encapsulation on the serial interfaces from PPP to HDLC

•

Intentionally break and restore PPP encapsulation

•

Configure PPP PAP and CHAP authentication

•

Intentionally break and restore PPP PAP and CHAP authentication

Scenario
In this lab, you will learn how to configure PPP encapsulation on serial links using the network
shown in the topology diagram. You will also learn how to restore serial links to their default
HDLC encapsulation. Pay special attention to what the output of the router looks like when you
intentionally break PPP encapsulation. This will assist you in the Troubleshooting lab associated
with this chapter. Finally, you will configure PPP PAP authentication and PPP CHAP
authentication.

Task 1: Prepare the Network
Step 1: Cable a network that is similar to the one in the topology diagram.
You can use any current router in your lab as long as it has the required interfaces shown in the
topology diagram.
Note: If you use 1700, 2500, or 2600 routers, the router outputs and interface descriptions appear
differently.
Step 2: Clear any existing configurations on the routers.

Task 2: Perform Basic Router Configuration
Configure the R1, R2, and R3 routers according to the following guidelines:
•

Configure the router hostname.

•

Disable DNS lookup.

•

Configure an EXEC mode password.

Task 3: Configure and Activate Serial and Ethernet Addresses
Step 1: Configure interfaces on R1, R2, and R3.
Configure the interfaces on the R1, R2, and R3 routers with the IP addresses from the addressing
table at the beginning of the lab. Be sure to include the clock rate on the serial DCE interfaces.

Configure the Ethernet interfaces of PC1 and PC3 with the IP addresses and default gateways
from the addressing table.
Step 4: Test the configuration by pinging the default gateway from the PC.

Task 4: Configure OSPF on the Routers
If you need to review the OSPF commands, see Exploration 2, module 11.
Step 1: Enable OSPF routing on R1, R2, and R3.
Use the router ospf command with a process ID of 1. Be sure to advertise the networks.
