CHAPTER 1

1. INTRODUCTION

The purpose of this document is to provide an MSc case study Report for the module CTP141N (Advance Routing Protocol) of MSc course in Network Management and Security taught by London Metropolitan University.

This document contains the design and implementation of two network scenarios for an international travel agency.

1.1 Scenario 1

Plan, design and implement complex EIGRP based Network for ITA.

Establish network connectivity between International Travel Agency (ITA) core network which is set up with EIGRP and a Local Travel agency (LTA) network which was running OSPF which ITA recently acquired.

1.2 Scenario 2

Plan, design and implement a complex BGP/OSPF based network for International Travel Agency.

Because International Travel Agency relies heavily on the internet for its advertising and sales, they need a redundant route to the internet, a backup route to avoid a single point of failure to the internet.

CHAPTER2

2.1 SUMMARY OF COMPANY Scenario 1

Company Name: International Travel Agency (ITA)

Acquired company name: Local Travel Agency (LTA)

2.1 NETWORK REQUIRMENT

* International Travel Agency (ITA) needs its core network to run EIGRP in AS 1.

* ITA core network is made up of three routers R1, R2, R3 and an Ethernet switch SW1

* summarize the loopback interfaces on R2 with the best possible summary to the other EIGRP routers

* Local Travel Agency (LTA) Router R4 needs to communicate with ITA core via OSPF area 0

* Redistribute OSPF into EIGRP

* originate a default router into OSPF process from R3

2.2 OBJECTIVE

Plan, design and implement the complex International Travel Agency (ITA) EIGRP network based on the above stated specifications,

Verify that all configurations are operational and functioning according to the guideline stated above

CHAPTER 4

4.1 COMPANY SUMMARY (SCENARIO 2)

Company name: International Travel Agency (ITA), with three branches in different geographical areas, London, Cape Town and San Jose

4.2 NETWORK REQUIRMENTS

* ITA relies heavily on the internet for its advertisements; therefore it has been decided to establish a primary and a backup route to the internet.

* ITA SanJose core routers must run OSPF in area 0

* London branch office in area 1 will be a totally stubby network

* Capetown branch office in Area 2 will be an Not so stubby area (NSSA)

* A third area will be a RIP subnet

* summarize all routes from each area into the core,

* Each area should have approximately 30 networks except Area 0

* Redistribute Routing information from RIP into OSPF, The RIP subnet should use default route to access the rest of the network and internet.

* Implement EZ IP for users in RIP subnet

* ITA network will be multihomed to ISP, primary link will be a T3 link connection, a backup T1 connection link will also be configured and will only be used when T3 goes down

* A firewall most be configured on sanjose3 router ASBR to allow all traffic originating inside AS 200, and deny any traffic outside 200 into the network

4.3 OBJECTIVE

Plan, design and implement the complex ITA network based on the above specified guidelines, and verify that all configurations are operational and functioning according to the guidelines.
