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.

ScenarioIn 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 clear 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 as "class".• Configure the following message-of-the-day banner: “Unauthorized access strictly prohibited and prosecuted to the full extent of the law".• Configure a password for console connections: “cisco”.• Configure a password for vty connections: “cisco”.• Save the running configuration to NVRAM.

All pings should be successful

Step 3: Verify the routing table.

R1#show ip route

R2#show ip route

R3#show ip route

Task 8: Configure OSPF Routing

Step 1: Configure OSPF routing on R1, R2, and R3.

R1

R1(config)#router ospf 1R1(config-router)#network 10.1.1.0 0.0.0.3 area 0R1(config-router)#network 10.12.12.0 0.0.0.255 area 0R1(config-router)#network 10.13.13.0 0.0.0.255 area 0R1(config-router)#network 192.168.10.0 0.0.0.255 area 0

R2

R2(config)#router ospf 1R2(config-router)#network 10.1.1.0 0.0.0.3 area 0R2(config-router)#network 10.2.2.0 0.0.0.3 area 0

7


R2(config-router)#network 10.12.12.0 0.0.0.255 area 0R2(config-router)#network 192.168.20.0 0.0.0.255 area 0

R3

R3(config)#router ospf 1R3(config-router)#network 10.2.2.0 0.0.0.3 area 0R3(config-router)#network 10.13.13.0 0.0.0.255 area 0R3(config-router)#network 192.168.30.0 0.0.0.255 area 0

Step 2: Verify that OSPF routes have replaced RIP routes because of lower administrative distance.

R1#show ip route

R2#show ip route

R3#show ip route

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.

R1#show ip rip database



Task 9: Configure EIGRP Routing

Step 1: Configure EIGRP routing on R1, R2, and R3.

R1

R1(config)#router eigrp 10R1(config-router)#no auto-summaryR1(config-router)#network 10.1.1.0 0.0.0.3R1(config-router)#network 10.12.12.0 0.0.0.255R1(config-router)#network 10.13.13.0 0.0.0.255R1(config-router)#network 192.168.10.0

R2

R2(config)#router eigrp 10R2(config-router)#no auto-summaryR2(config-router)#network 10.1.1.0 0.0.0.3R2(config-router)#network 10.2.2.0 0.0.0.3R2(config-router)#network 10.12.12.0 0.0.0.255R2(config-router)#network 192.168.20.0

R3

R3(config)#router eigrp 10R3(config-router)#no auto-summaryR3(config-router)#network 10.2.2.0 0.0.0.3R3(config-router)#network 10.13.13.0 0.0.0.255R3(config-router)#network 192.168.30.0

Step 2: Verify that EIGRP routes have replaced OSPF routes because of lower administrative distance.

R1#show ip route

R2#show ip route

R3#show ip route

Step 3: Verify that OSPF is still running.

R1#show ip ospf database
