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.
Configure a message-of-the-day banner.
Configure a password for console connections.
Configure synchronous logging.
Configure a password for vty connections.

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.
