Basic EIGRP for IPv4 Introduction EIGRP is an enhanced version of IGRP. The same distance vector technology found in IGRP is also used in EIGRP, and the underlying distance information remains unchanged. The convergence properties and the operating efficiency of this protocol have improved significantly. Although EIGRP has Link State routing protocol characteristics, EIGRP falls under the Distance Vector routing protocol classification and is referred to as an advanced Distance Vector routing protocol instead. EIGRP runs directly over IP. Objective(s) In this lab the student will: ● Build the Network and Verify Connectivity ● Configure EIGRP Routing ● Verify EIGRP Routing ● Configure Passive Interfaces ● Disable Auto summarization Equipment/Supplies Needed ● Your computer workstation ● Cisco Packet Tracer ● Basic EIGRP for IPv4.pkt file 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 the end of this lab for the correct interface identifiers. ITNW 2312 Lab 3.1.1a Basic EIGRP

Make sure that the routers have been erased and have no startup configurations. If you are unsure, contact your instructor.

Topology Procedure Perform the steps in this lab in the order they are presented to you. Answer all questions and record the requested information in a file. Part 1: Build the Network and Verify Connectivity In Part 1, you will set up the network topology and configure basic settings, such as the interface IP addresses, device access, and passwords. Step 1: Configure PC hosts. Step 2: Initialize and reload the routers as necessary. Step 3: Configure basic settings for each router. ITNW 2312 Lab 3.1.1a Basic EIGRP

● Disable DNS lookup. ● Configure IP addresses for the routers, as listed in the Addressing Table. ● Configure device name as shown in the topology. ● Assign cyber as the console and vty passwords. ● Assign security as the privileged EXEC password. ● Configure logging synchronous to prevent console and vty messages from interrupting command entry. ● Configure a message of the day. “ Unauthorized Access is Prohibited ”. ● Copy the running configuration to the startup configuration. Step 4: The routers should be able to ping one another, and each PC should be able to ping its default gateway. The PCs will not be able to ping other PCs until EIGRP routing is configured. Verify and troubleshoot if necessary. Part 2: Configuring EIGRP Step 1: Enable EIGRP routing on R1. Use AS number 10. R1(config)# router eigrp 10 What is the range of numbers that can be used for AS numbers? 1-65535 Step 2: Advertise the directly connected networks on R1 using the wildcard mask. Use the show ip route command to display the directly connected networks on each router. ITNW 2312 Lab 3.1.1a Basic EIGRP
