An Analysis Of The EGP, Border Gateway Protocol

Decent Essays

Moving away from IGP, now I will discuss the one and only EGP standard used over the Internet, the BGP, Border Gateway Protocol, each version is just a slight enhancement over the previous one. As mentioned before an EGP’s purpose is to connect one autonomous system to a different autonomous system and version 4 has been updated to accept classless domains as well as support for IPv6. It also introduces a system to cut back on the amount of routing tables needed for a network and can support most polices due to the internet being a hop-count like routing model, and BGP-4 supports hop counts. Not only that, it is a reliable protocol because it uses the Transmission Control Protocol from the Transport Layer, which eliminates the need for …show more content…

The autonomous systems use BGP to be visible to networks outside of it's on AS, each AS is allowed to create its own policy, allowing for the way in which the information should be routed. And lastly, because each autonomous system has its own set of protocols, the IGP, where one or more is used to discover the connections inside that network. (Lammle 928) I see it as everything as its own responsibility within, allowing for BGP which is both versatile and flexible to meet the demands of the packets that need to be forwarded, because everything has its own task and its own set of rules making the procedure orderly and efficient.
The only similarity that RIP and BGP have is that they are routing protocols and route information by using an algorithm to send the packets, otherwise they are different in many aspects. One of the biggest differences between RIP and BGP is that RIP is an IGP and BGP is an EGP, but you can say they work together to get their task done. If information from an autonomous system that has RIP needs to send information to another autonomous within its limit of 15 hop counts, BGP helps to bridge that gap. The other biggest difference is RIP is a simple protocol meant for the use of a small network, while BGP is vast and a highly complex protocol that can be considered as the management system of transferring data of numerous amounts of autonomous systems. BGP can also be seen as the major backbone
