CASE STUDY 8 INTEGRATING EIGRP (ENHANCED INTERIOR

GATEWAY ROUTING PROTOCOL) INTO EXISTING NETWORKS

The case study should provide the benefits and considerations involved in integrating Enhanced

IGRP into the following types of internetworks:

IPThe existing IP network is running IGRP

Novell IPXThe existing IPX network is running RIP and SAP

AppleTalkThe existing AppleTalk network is running the Routing Table Maintenance

Protocol (RTMP)

When integrating Enhanced IGRP into existing networks, plan a phased implementation. Add

Enhanced IGRP at the periphery of the network by configuring Enhanced IGRP on a boundary

router on the backbone off the core network. Then integrate Enhanced IGRP into the core

network

REQUIREMENTS:

Three CISCO 2811 routers.

Three 24 Port CISCO switch.

Copper Straight through cables.

Three Serial Line cables.

Nine Windows PCs

Class A and Class C IP Address.

EIGRP Routing protocol Configuration commands.

Basic Network configuration commands.

Cisco Packet Tracer 6.0.1.exe

PROCEDURES:

What is EIGRP?

Enhanced Interior Gateway Routing Protocol

Advanced distance vector

Rapid convergence

100% loop-free classless routing

Easy configuration

Incremental updates

Load balancing across equal- and unequal-cost pathways

Flexible network design

Multicast and unicast instead of broadcast address

Support for VLSM and discontinuous subnets

Manual summarization at any point in the internetwork

Support for multiple network layer protocols


Features of EIGRP:

Cisco proprietary protocol

Classless routing protocol

Includes all features of IGRP

Metric (32 bit) : Composite Metric (BW + Delay + load + MTU + reliability )

Administrative distance is 90

Updates are through Multicast (224.0.0.10 )

Max Hop count is 255 (100 by default)

Supports IP, IPX and Apple Talk protocols

Hello packets are sent every 5 seconds

Convergence rate is fast

Overcome The RIP limitations.

NETWORK TOPOLOGY:


EIGRP Tables:

EIGRP routing Protocol maintains three tables for best routing or path selection to destination

Network.

Neighbor Table

Topology Table

Routing Table

Disadvantages of EIGRP:

Works only on Cisco Routers
