Router

•      A router receives and sends data in computer networks.
•      Improve access to the Internet.
•     Help create business networks.
•      A common tool for modern network computing, routers
•   They connect employees to local networks and the Internet, where almost all essential business activities take place.
•   Providing security, integrated firewall and content filtering software provides additional protection against unwanted content and malicious websites, without affecting the online experience.

Routing Table

 The routing table is a document, organized in a hierarchical structure that is used to speed up the search process when locating routes and forwarding packets. Within this structure, the hierarchy includes several levels (level 1 and level 2). The routing table consists of route entries from the following sources:

•     Directly connected networks.
•     Static routes.
•     Dynamic Routing Protocols.

Static Routing

      Static routing can become the solution for small networks because of its security and economy of resources; it does not consume bandwidth, does not make the router CPU work and is easy to configure.

      Unlike when configuring a network with dynamic routing protocols, static routing configuration requires administrator intervention each time changes are made to the network.

Dynamic Routing

 Routing protocols are used to facilitate the exchange of routing information between routers. A routing protocol is a set of processes, algorithms and messages that are used to exchange routing information and complete the routing table by choosing the best paths that the protocol performs.

• The purpose of dynamic routing protocols includes the following:
•  Discovering remote networks
• Keep routing information up to date
• Choosing the best path to the destination networks
• To be able to find a better new route if the current one is no longer available.

Protocol

      The protocol is defined as the rules for the transmission of information between two points. A data communication network protocol is a set of rules that governs the orderly exchange of data within the network.

RIP

      The Routing Information Protocol (RIP) is a vector-distance routing protocol, in use in thousands of networks worldwide. RIP is based on an open standard, described in RFC 1058, which is easy to implement, although RIP lacks the capability and features of more advanced routing protocols. In principle, the RIP protocol divides the participating machines into active or passive. Only routers can run RIP in active mode, so machines must run RIP in passive mode.

OSPF

 The Open Shortest Path First (OSPF) protocol, defined in RFC 2328, is an Internal Gateway Protocol (IGP) used to distribute routing information within a single autonomous system. The OSPF protocol was developed due to the need within the Internet community to introduce a non-proprietary, highly functional Internal Gateway Protocol (IGP) for the TCP/IP protocol family. Discussion on the creation of a common interoperable IGP for the Internet began in 1988 and was not formalized until 1991.

IGRD

 The Internal Gateway Routing Protocol (IGRP) is a proprietary protocol of CISCO. It is a vector-distance routing protocol. This protocol can consider bandwidth, load, delay, and reliability to create a composite metric. IGRP sends, by default, routing table updates for a particular standalone system at 90 second intervals. Unlike RIP, the IGRP protocol in its enhanced version (EIGRP) allows for large network operations.

EIGRD

 The EIGRP is an enhanced version of the IGRP. The equal distance vector technology used in IGRP is also used in EIGRP. In addition, the underlying distance information remains unchanged. The convergence properties and operating efficiency of this protocol have been significantly improved. This allows for improved architecture while retaining the existing investment in IGRP.

Router Configuration

1.    Unpack the router and connect it to a power source.

2.    Connect one end of the network cable to the computer's wired network adapter and the other end to a port on the wireless router's LAN (any port that is not labeled "Internet," "WAN," or "uplink").

3.    Open your Web browser and enter the address of the router's configuration web page. For most routers, the address of the configuration web page is http://192.168.0.1 or http://192.168.1.1.
