Chapter 2 Lab 2-1, EIGRP Configuration, Bandwidth, and Adjacencies

Topology

Objectives

• Configure EIGRP on multiple routers.
• Configure the bandwidth command to modify the EIGRP metric. • Verify EIGRP adjacencies.
• Verify EIGRP routing information exchange.
• Use debugging commands for troubleshooting EIGRP.
• (Challenge) Test convergence for EIGRP when a topology change occurs.

Background

You are responsible for configuring a new network to connect your company’s Engineering, Marketing, and Accounting departments, represented by the loopback interfaces on each of the three routers. The physical devices have just been installed and are connected by Fast Ethernet and serial interfaces. Your task is to configure EIGRP to enable full connectivity between all departments.

Note: This lab uses Cisco 1841 routers with Cisco IOS Release 12.4(24)T1 and the Advanced IP Services image c1841-advipservicesk9-mz.124-24.T1.bin. The switch is a Cisco WS-C2960-24TT-L with the Cisco IOS image c2960-lanbasek9-mz.122-46.SE.bin. You can use other routers (such as 2801 or 2811), switches (such as 2950), and Cisco IOS Software versions if they have comparable capabilities and features. Depending on the router or switch model and Cisco IOS Software version, the commands available and output produced might vary from what is shown in this lab.

Required Resources

• 3 routers (Cisco 1841 with Cisco IOS Release 12.4(24)T1 Advanced IP Services or comparable) • 1 switch (Cisco 2960 with the Cisco IOS Release 12.2(46)SE C2960-LANBASEK9-M image or comparable) • Serial and Ethernet cables

Step 1: Configure addressing and loopbacks.

a. Using the addressing scheme in the diagram, apply IP addresses to the Fast Ethernet interfaces on R1, R2, and R3. Then create Loopback1 on R1, Loopback2 on R2, and Loopback3 on R3 and address them according to the diagram.

R1# configure terminal
R1(config)# interface Loopback1
R1(config-if)# description Engineering Department
R1(config-if)# ip address 10.1.1.1 255.255.255.0
R1(config-if)# exit
R1(config)# interface FastEthernet0/0
R1(config-if)# ip address 10.1.100.1 255.255.255.0
R1(config-if)# no shutdown

R2# configure terminal
R2(config)# interface Loopback2
R2(config-if)# description Marketing Department
R2(config-if)# ip address 10.1.2.1 255.255.255.0
R2(config-if)# exit
R2(config)# interface FastEthernet0/0
R2(config-if)# ip address 10.1.100.2 255.255.255.0
R2(config-if)# no shutdown

R3# configure terminal
R3(config)# interface Loopback3
R3(config-if)# description Accounting Department
R3(config-if)# ip address 10.1.3.1 255.255.255.0
R3(config-if)# exit
R3(config)# interface FastEthernet0/0
R3(config-if)# ip address 10.1.100.3 255.255.255.0
R3(config-if)# no shutdown

Leave the switch in its default (blank) configuration. By default, all switch ports are in VLAN1 and are not administratively down.

Note: If the switch has been previously configured, erase the startup config, delete the vlan.dat file from flash memory, and reload the switch.

For now, also leave the serial interfaces in their default configuration. You will configure the serial link between R1 and R2 in Step 4.

b. Verify that the line protocol of each interface is up and that you can successfully ping across each link. You should see output similar to the following on each router.

R1# show ip interface brief
Interface IP-Address OK? Method Status Protocol FastEthernet0/0 10.1.100.1 YES manual up up FastEthernet0/1 unassigned YES unset administratively down down Serial0/0/0 unassigned YES manual administratively down down Serial0/0/1 unassigned...
