Routing 1protocols determines the shortest path to transfer the data from one host to another and specify how communication takes place between each routers. There are different classes of routing protocols are available in different environments such as intra and inter Autonomous System (AS).A routing protocol can be static or dynamic as well as link state and path vector. We will focus on Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP), OSPF and BGP protocols are dynamic in nature. BGP is an inter-autonomous system routing protocol and OSPF is an intra-a utonomous system routing protocol. We can analyze the performance of Wide Area Network (WAN) by enabling the Interior Gateway Protocol (IGP) and Exterior Gateway Protocol (EGP) of the network and ensure the Quality of Service (QoS).
