COM524: EIGRP Practical Exercise

This practical exercise introduces EIGRP routing protocol. Students are tasked with designing a network scheme using a single network address (192.168.0.X) to accommodate 50 hosts on the Paris router and 25 on the Warsaw router. The exercise involves configuring routers and hosts, troubleshooting network connectivity, configuring EIGRP on both routers, viewing routing tables and topology tables, and analyzing EIGRP statistics using various show commands. Students are required to configure interfaces, assign IP addresses, subnet masks, and default gateways. They will then use ping to test connectivity and troubleshoot any issues. The exercise culminates in analyzing EIGRP neighbor relationships, topology tables, and key performance indicators using show commands to understand the routing process and network performance.

Practical Exercise: 6 – EIGRP
This tutorial is intended as an introduction to EIGRP. It assumes that the student is
familiar with various Routing Protocols. Design a networking scheme you have only
been allocated 1 network address which is 192.168.0.X. Allow for 50 hosts on the
Paris Router and 25 on the Warsaw Router.

Step 1 Configure the routers
On the routers, enter the global configuration mode and configure the hostname as
shown in the table. Then configure the console, virtual terminal and enable
passwords. Next configure the interfaces according to the chart. Finally, configure the
IP hostnames. Do not configure the routing protocols.
Step 2 Configure the hosts with the IP address, subnet mask and
default gateway
a. Each workstation should be able to ping the attached router. Troubleshoot as
necessary. Remember to assign a specific IP address and default gateway to the
workstation. Check by using the ipconfig command in a DOS window.
b. At this point the workstations will not be able to communicate with each other. The
following steps will demonstrate the process required to get communication working
using EIGRP as the routing protocol.
Step 3 View the routers configuration and interface information
Paris#show running-config
a. Using the show ip interface brief command, check the status of each interface.
b. Ping from one of the connected serial interfaces to the other - troubleshoot the
routers configuration, until the ping is successful.

Step 4 Configure EIGRP routing on router Paris
a. Enable the EIGRP routing process on Paris, and configure the networks it will
advertise. Use EIGRP autonomous system number 101.
Paris(config)#router eigrp 101
Paris(config-router)#network (ip address + Wild Card Mask of Fast ethernet
network )
Paris(config-router)#network (ip address + Wild Card Maskof Serial
network)
Paris(config-router)#network (ip address + Wild Card Mask of Loopback
network)
Paris(config-router)#end
b. Show the routing table for the Paris router.
Paris#show ip route
Step 5 Configure EIGRP routing on router Warsaw
a. Enable the EIGRP routing process on Warsaw, and configure the networks it will
advertise. Use EIGRP autonomous system number 101.
Warsaw(config)#router eigrp 101
Warsaw(config-router)# network (ip address + Wild Card Mask of Fast
ethernet network )
Warsaw(config-router)# (ip address + Wild Card Maskof Serial network)
Warsaw(config-router)#end
b. Show the routing table for the Warsaw router.
Warsaw#show ip route
Step 6 Show EIGRP neighbors
a. From the Paris router show any neighbors connected using the show ip eigrp
neighbors command at the privileged EXEC mode prompt.
Step 7 View the topology table
a. To view the topology table, issue the show ip eigrp topology all-links command.
b. How many routes are in passive mode? _______________________________
c. To view more specific information about a topology table entry, use :
Paris#show ip eigrp topology (ip address of Serial network)
d. Does the output of this command tell you what external protocol originated this
route to (ip address of Fast ethernet network on Warsaw)? _________________________
e. Does it tell which router originated the route? ______________________________
f. Use show commands to view key EIGRP statistics. On the Paris router, issue the
show ip eigrp traffic command.
g. How many hello packets has the Paris router received? ______________________
h. By using show interface for Serial, PC & Server fill in this information:
Hardware is ............. Bandwidth ......... Delay ......... Reliability .........
txload ......... rxload ......... Encapsulation .........

Use show sh ip eigrp topology (using ip address) to find the Composite metric _____
