Background / Scenario
EIGRP has advanced features to allow changes related to summarization, default route propagation, bandwidth utilization, and metrics.
In this lab, you will configure automatic summarization for EIGRP, configure EIGRP route propagation, and fine-tune EIGRP metrics.
Note: The routers used with CCNA hands-on labs are Cisco 1941 Integrated Services Routers (ISRs) with Cisco IOS Release 15.2(4)M3 (universalk9 image). Other routers and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and output produced might vary from what is shown in the labs. Refer to the Router Interface Summary Table at this end of the lab for the correct interface identifiers.
Note: Ensure that the routers have been erased and have no startup configurations. If you are unsure, contact your instructor.
Instructor Note: Refer to the Instructor Lab Manual for the procedures to initialize and reload devices.
Required Resources
- 3 Routers (Cisco 1941 with Cisco IOS Release 15.2(4)M3 universal image or comparable)
- 3 PCs (Windows with a terminal emulation program, such as Tera Term)
- Console cables to configure the Cisco IOS devices via the console ports
- Ethernet and serial cables as shown in the topology
Part 1: Build the Network and Configure Basic Device Settings
In Part 1, you will set up the network topology and configure basic settings on the PC hosts and routers.
Step 1: Cable the network as shown in the topology.
Step 2: Configure PC hosts.
Step 3: Initialize and reload the routers as necessary.
Step 4: Configure basic settings for each router.
a. Disable DNS lookup.
b. Configure device name as shown in the topology.
c. Assign cisco as the console and vty passwords.
d. Assign class as the privileged EXEC password.
e. Configure logging synchronous to prevent console messages from interrupting command entry.
f. Configure the IP address listed in the Addressing Table for all interfaces.
Note: Do NOT configure the loopback interfaces at this time.
g. Copy the running configuration to the startup configuration.
Part 2: Configure EIGRP and Verify Connectivity
In Part 2, you will configure basic EIGRP for the topology and set bandwidths for the serial interfaces.
Note: This lab provides minimal assistance with the actual commands necessary to configure EIGRP. However, the required commands are provided in Appendix A. Test your knowledge by trying to configure the devices without referring to the appendix.
Step 1: Configure EIGRP.
a. On R1, configure EIGRP routing with an autonomous system (AS) ID of 1 for all directly connected networks. Write the commands used in the space below.
___________________________________________________
R1(config)# router eigrp 1
R1(config-router)# network 192.168.1.0
R1(config-router)# network 192.168.12.0 0.0.0.3
R1(config-router)# network 192.168.13.0 0.0.0.3
b. For the LAN interface on R1, disable the transmission of EIGRP hello packets. Write the command used in the space below.
___________________________________________________
R1(config-router)# passive-interface g0/0
c. On R1, configure the bandwidth for S0/0/0 to 1024 Kb/s and the bandwidth for S0/0/1 to 64 Kb/s. Write the commands used in the space below. Note: The bandwidth command only affects the EIGRP metric calculation, not the actual bandwidth of the serial link.
___________________________________________________
R1(config)# interface s0/0/0
R1(config-if)# bandwidth 1024
R1(config-if)# interface s0/0/1
R1(config-if)# bandwidth 64
d. On R2, configure EIGRP routing with an AS ID of 1 for all networks, disable the transmission of EIGRP hello packets for the LAN interface, and configure the bandwidth for S0/0/0 to 1024 Kb/s.
e. On R3, configure EIGRP routing with an AS ID of 1 for all networks, disable the transmission of EIGRP hello packets for the LAN interface, and configure the bandwidth for S0/0/0 to 64 Kb/s.
Step 2: Test connectivity.
All PCs should be able to ping one another. Verify and troubleshoot if necessary.
Note: It may be necessary to disable the PC firewall to ping between PCs.
Part 3: Configure EIGRP for Automatic Summarization
In Part 3, you will add loopback interfaces and enable EIGRP automatic summarization on R1 and R3. You will also observe the effects on the routing table of R2.
Step 1: Configure EIGRP for automatic summarization.

The 192.168.11.0 networks are summarized at their classful boundary.
f. Repeat substeps b through e by adding loopback interfaces, adding EIGRP process networks and auto-summary on R3.
Part 4: Configure and Propagate a Default Static Route
In Part 4, you will configure a default static route on R2 and propagate the route to all other routers.
a. Configure the loopback address on R2.
b. Configure a default static route with an exit interface of Lo1.
R2(config)# ip route 0.0.0.0 0.0.0.0 Lo1
c. Use the redistribute static command within the EIGRP process to propagate the default static route to other participating routers.
R2(config)# router eigrp 1 R2(config-router)# redistribute static
d. Use the show ip protocols command on R2 to verify the static route is being distributed.

D*EX 0.0.0.0/0 [170/3139840] via 192.168.12.2, 00:06:27, Serial0/0/0
The administrative distance is 170 as it is an external EIGRP route.
Part 5: Fine-Tune EIGRP
In Part 5, you will configure the percentage of bandwidth that can be used for EIGRP traffic on an interface and change the hello interval and hold timers for EIGRP interfaces.
Step 1: Configure bandwidth utilization for EIGRP.
a. Configure the serial link between R1 and R2 to allow only 75 percent of the link bandwidth for EIGRP traffic.
R1(config)# interface s0/0/0 R1(config-if)# ip bandwidth-percent eigrp 1 75 R2(config)# interface s0/0/0 R2(config-if)# ip bandwidth-percent eigrp 1 75
b. Configure the serial link between R1 and R3 to allow 40 percent of the links bandwidth for EIGRP traffic.
Step 2: Configure the hello interval and hold timer for EIGRP.
a. On R2, use the show ip eigrp interfaces detail command to view the hello interval and hold timer for EIGRP.
R2# show ip eigrp interfaces detail EIGRP-IPv4 Interfaces for AS(1) Xmit Queue PeerQ Mean Pacing Time Multicast Pending Interface Peers Un/Reliable Un/Reliable SRTT Un/Reliable Flow Timer Routes Se0/0/0 1 0/0 0/0 1 0/15 50 0 Hello-interval is 5, Hold-time is 15 Split-horizon is enabled Next xmit serial <none> Packetized sent/expedited: 29/1 Hello's sent/expedited: 390/2 Un/reliable mcasts: 0/0 Un/reliable ucasts: 35/39 Mcast exceptions: 0 CR packets: 0 ACKs suppressed: 0 Retransmissions sent: 0 Out-of-sequence rcvd: 0 Topology-ids on interface - 0 Interface BW percentage is 75 Authentication mode is not set Se0/0/1 1 0/0 0/0 1 0/16 50 0 Hello-interval is 5, Hold-time is 15 Split-horizon is enabled Next xmit serial <none> Packetized sent/expedited: 34/5 Hello's sent/expedited: 382/2 Un/reliable mcasts: 0/0 Un/reliable ucasts: 31/42 Mcast exceptions: 0 CR packets: 0 ACKs suppressed: 2 Retransmissions sent: 0 Out-of-sequence rcvd: 0 Topology-ids on interface - 0 Authentication mode is not set
What is the default value for hello time? ____________5 seconds
What is the default value for hold time? ____________15 seconds
b. Configure S0/0/0 and S0/0/1 interfaces on R1 to use a hello interval of 60 seconds and a hold time of 180 seconds in that specific order.
R1(config)# interface s0/0/0 R1(config-if)# ip hello-interval eigrp 1 60 R1(config-if)# ip hold-time eigrp 1 180 R1(config)# interface s0/0/1 R1(config-if)# ip hello-interval eigrp 1 60 R1(config-if)# ip hold-time eigrp 1 180
c. Configure the serial interfaces on R2 and R3 to use a hello interval of 60 seconds and a hold time of 180 seconds.
d. Use the show ip eigrp interfaces detail command on R2 to verify configuration.
R2# show ip eigrp interfaces detail

Reflection
1. What are the benefits of summarizing routes?
_______________________________________________________
Summarization can be used to limit the number of routing advertisements and the size of routing tables.
2. When setting EIGRP timers, why is it important to make the hold time value equal to or greater than the hello interval?
_______________________________________________________
If the hold time is less than the hello interval, the neighbor adjacency will go down.

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many interfaces the router has. There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device. The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface. |
