• Configure basic EIGRP parameters.
• Configure EIGRP route summarization.
• Configure EIGRP - OSPF redistribution.
Equipment
l Two Cisco model 2621 routers, each with one T1/FT1 interface and two fast-Ethernet interfaces.
l One Cisco model 2620 router with two T1/FT1 interface and one fast-Ethernet interfaces.
l Two back-to-back T1 cables
Initial Configuration
Assign the following IP Addresses to the routers:
Task 1: Basic EIGRP Configuration
1. Enable EIGRP on all routers. Place all routers in autonomous system 75. Using classful network statements,
include all interfaces on each router.
2. Verify IP connectivity by pinging Loopback0 on Router A (70.70.0.1) from Router C.
Task 2: Configure EIGRP Route Summarization
1. Can Router C ping FastEthernet0/1 (80.160.1.1) on Router A? Why or why not?
2. Can Router A ping Loopback0 (80.80.0.1) on Router C? Why or Why not?
3. Disable auto-summarization on all routers.
4. Configure Router B to summarize the 70.0.0.0 /8 network when distributing it to Router C
5. Configure Router B to summarize the 80.80.0.0 /16 network when distributing it to Router A.
6. Verify that Router C can ping 80.160.1.1.
7. Verify that Router A can ping 80.80.0.1.

Task 3: Configure EIGRP - OSPF Redistribution
1. Remove EIGRP configuration for the 80.0.0.0 /8 network:
¡ Remove network 80.0.0.0 statement from Router B.
¡ Remove ip summary-address statements from S0/1 and S0/0 interfaces on Router B.
2. Configure OSPF on Router C:
¡ Process ID = 80.
¡ Use one classful network statement that captures all interfaces.
¡ Make all interfaces reside in Area 0.
3. Configure OSPF on Router B:
¡ Process ID = 80.
¡ Use one classful network statement that captures all interfaces.
¡ Make all interfaces reside in Area 0.
4. Redistribute EIGRP routes into OSPF on Router B:
¡ Use the OSPF router configuration command redistribute eigrp 75 subnets
5. Redistribute OSPF routes into EIGRP on Router B:
¡ Assign all redistributed OSPF routes the metric of a directly connected T1.
6. Verify connectivity by pinging Loopback0 on Router C (80.80.0.1) from Router A.

Task 2
1. No. That route never makes it to Router C. Router A advertises a summary route (80.0.0.0 /8) to Router B. So
Router C does have a route to 80.0.0.0 pointing to Router B that's where it sends the packets. Router B's
route to 80.0.0.0 points to NULL0, so the packets are dropped.
2. No. Router A has a summary route to 80.0.0.0 /8 pointing to NULL0, so the packet is dropped.

EIGRP Lab #2
Goals
• Configure basic EIGRP parameters.
• Configure EIGRP bandwidth utilization.
• Configure EIGRP load balancing.
Equipment
l Four Cisco model 2620 routers, each with two T1/FT1 interfaces and one fast-Ethernet interface.
l Four back-to-back T1 cables.
l Two PCs.
Initial Configuration
1. Assign the following IP Addresses to the equipment:
CertificationZone Page 10 of 15
http://www.certificationzone.com/studyguides /?Issue=29&IssueDate=01-01-2001&CP= 11/06/01
2. To the serial links assign the following bandwidth values:
Router A to Router B = 128 Kb/s
Router B to Router D = 512 Kb/s
Router D to Router C = 256 Kb/s
Router C to Router A = 128 Kb/s
Task 1: Basic EIGRP Configuration
1. Enable EIGRP on all routers. Place all routers in autonomous system 75. Using classful network statements,
include all interfaces on each router.
2. Verify connectivity by pinging from PC1 to PC2.
Task 2: Configure EIGRP Bandwidth Utilization
1. Prevent data traffic on the 128 Kb/s links from being affected by EIGRP traffic. Configure them to use a
maximum of 10% of their bandwidth for EIGRP.
2. Prevent output queues on the 128 Kb/s links from overflowing. Increase the output queue size by 25%.
Task 3: Configure EIGRP Load Balancing
1. Under the current configuration, will traffic from LAN1 to LAN2 be load balanced over the two available paths?
Why or why not?
2. Verify load balancing with the following (unscientific) test:
¡ Disable fast-switching interfaces S0/0 and S0/1 of Router A. This is done in interface configuration
mode with the command no ip route-cache.
¡ Run two or three concurrent traceroutes from PC1 to PC2.
3. How would you configure unequal-cost load balancing such that most of the traffic from LAN 1 to LAN 2 (and
back) uses the path via Router B.
4. Configure unequal-cost load balancing on Routers A and D to cause most of the traffic from LAN 1 to LAN 2
(and back) to use the path via Router B.
5. Verify that Router A has two unequal-cost feasible successors to LAN 2.
6. Verify that Router D has two unequal-cost feasible successors to LAN 1.
