Introduction


The purpose of routing protocols is to learn of available routes that exist on the enterprise network, build routing tables and make routing decisions. Some of the most common routing protocols include IGRP, EIGRP, OSPF, and BGP. (BGP is not part of CCNA syllabus   There are two primary routing protocol types although many different routing protocols defined with those two types

 Types of Routing protocol :  



1 Static Routing protocol :-   Static routing is a form of routing that occurs when a router uses a manually-configured routing entry,
ather than information from a dynamic routing traffic.In many cases, static routes are manually configured by a network administrator by adding in entries into a routing table,

Static routing can also be used in stub networks, or to provide a gateway of last resort.

Static routing may have the following uses:
  • Static routing can be used to define an exit point from a router when no other routes are available or necessary. This is called a default route.
  • Static routing can be used for small networks that require only one or two routes. This is often more efficient since a link is not being wasted by exchanging dynamic routing information.
  • Static routing is often used as a complement to dynamic routing to provide a failsafe backup in the event that a dynamic route is unavailable.
  • Static routing is often used to help transfer routing information from one routing protocol to another (routing redistribution).
