Designing a Comprehensive Network Topology Using BGP Attributes in GNS3

The Border Gateway Protocol (BGP), known also as an Exterior Gateway Protocol (EGP), is used frequently by Internet networks to exchange routing information among various autonomous systems (ASs). BGP is divided into two variations. The internal variation exchanges the data between two neighbours in the same an AS, while the external BGP is responsible for exchanging packets among different ASs. BGP has path-vector protocols that are used to select a path to a remote network based on routing policy. This research aims to investigate and implement BGP protocols in different attributes by using GNS3 software. The second goal is delivering a good tutorial with no complexity that would lead to comprehensive understanding of the BGP routing features with different attributes. In this dissertation, Graphical Network Simulator version 3 (GNS3) emulator software is used to design the practical network. Students in MSc networking professional and one MSc Advanced Computer Network course student were chosen to test the implementation and were interviewed for feedback used to improve the work
