The main objective of this paper is to describe the incoming and outgoing traffic and to maintain integrity through networking tools as well. It also consists of the multiple routing protocols in different areas of the country wide WAN. It is generally concern with the proper movement of the packet from one part of the country to the other part of the country. Along with previous concept, it also consists of various networking protocols and their implementation in simulation mode. The paper explains that how from one’s location computer, the packet moves out and reaches the same local ISP. It also describes the implementation of Packet Tracer to configure WAN network and its associated features. Since, cost of routers, switches, hubs, and various networking devices are much more which is beyond the approach of common learners. So, Packet Tracer is very helpful to configure various topologies in simulation mode which is act as a simulator. It often contains various routers, switches, different types of wired as well as wireless devices through graphical user interface (GUI) to required users. In configuring WAN network, there are various networking tools are also used which plays a very important role in making various networks on which various networking protocols can be implemented. Different networking devices works at different internet layers like IP layer, application layer etc. Through which different incoming and outgoing traffic can be carried out. Router can forward the packet from one logical network to another logical network by identifying its routing table which contains various information in row and column format such that intersection of each row and each column contains the entries for one particular network.
