What are Top 5 Network Routing Protocols ?

There is lots of different protocols for communicating between computers. So routing protocols are the family of network protocols. How routing protocols work ? Recognize other computer router on the network. Next keep track of all the possible destination along with some data explaining the pathaway of each. Then determin about where to where to send each network message. We talk about Top 5 Network Routing Protocols in the following:

RIP

The Routing Information Protocol (RIP) is one of a family of IP Routing protocols, and is an Interior Gateway Protocol (IGP) designed to distribute routing information within an Autonomous System (AS). RIP sends the complete routing table out to all active interfaces every 30 seconds.  It uses broadcast to share routing information.

OSPF

OSPF is an interior gateway protocol (IGP) for routing Internet Protocol (IP) packets solely within a single routing domain, such as an autonomous system.  advantage of OSPF is that the complete knowledge of topology allows routers to calculate routes that satisfy particular criteria and s a reduction in the number of routes to propagate – by the filtering and the summarization of routes.  And has better convergence than RIP.

EIGRP and IGRP

IGRP stands for Interior Gateway Routing Protocol; and EIGRP stands for Enhanced IGRP.

EIGRP  is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration. Maximum hop count for IGRP and EIGRP routed packets is 255. Default is 100. EIGRP has totally replaced the obsolete IGRP

IS-IS

The IS-IS (Intermediate System – Intermediate System) protocol is one of a family of IP Routing protocols,  IS-IS does not run over Internet Protocol (IP) Each IS-IS router distributes information about its local state. t accomplishes this by determining the best route for data through a packet-switched network.

BGP and EGP

Border Gateway Protocol (BGP) is a standardized exterior gateway protocol. BGP routing information is usually exchanged between competing business entities in the form of internet service providers. Exterior Gateway Protocol (EGP) is a protocol for exchanging routing information between two neighbor gateway hosts.
