Abstract

Routing protocols are used by routers or higherlevel switch interconnection. The most used protocols are the following: Routing Information Protocol (RIP), Interior Gateway Routing Protocol (IGRP), Open Shortest Path First (OSPF), Intermediate System to Intermediate System (IS-IS), and Border Gateway Protocol (BGP). Some of them are used as internal, while some of them are used as external for connecting to the Internet autonomous systems. One of the most used connection status routing protocols is the Open Shortest Path First (OSPF). The advantage of this protocol is a high speed of the connection recovery and low network traffic. This paper demonstrates the application of protocols in switched networks. A practical solution is shown for enhancement of the existing data and communication network into one unique system with redundant connections between locations. Instead of using the routing protocols that are related to one producer, this example shows a possibility of the system upgrade and adding different network segments of other producers. A conclusion can be reached that the use of OSPF protocols provides great advantage as opposed to other connection status protocols and distance vector protocols.
