Routing is the prime factor in this modern era of internet communication. Several routing protocols are in existence in these days. The routing of packets between IP networks is carried out by two different ways i.e. static routing & dynamic routing. In static routing, static routes are usually manually configured by network administrator by adding entries into routing table though this may not always be the case. Dynamic routing is widely used for big IP networks. The most commonly used dynamic routing protocols are RIP (Routing Information Protocol), OSPF (Open Shortest Path First), IGRP (Interior Gateway Routing Protocol) and EIGRP (Enhanced Interior Gateway Routing Protocol).
