DIFFERENT TYPE OF PROTOCOLS

Today i am going to discuss classification of ROUTING PROTOCOLS.
let me discuss different type/class of routing protocols
.
basically routing protocols is divided into two parts-
1> INTERIOR GATEWAY PROTOCOL
2> EXTERIOR GATEWAY PROTOCOL

now INTERIOR GATEWAY PROTOCOL is divided into two parts
1>DISTANCE VECTOR ROUTING PROTOCOLS
2>LINK STATE ROUTING PROTOCOLS

now DISTANCE VECTOR ROUTING PROTOCOLS is divided into 3 parts and i am also giving example of each one

1>CLASSFUL-- RIP and IGRP are example of classful routing protocols where IGRP is cisco proprietary

2>CLASSLESS--RIPV2 and EIGRP are example of classless routing protocols where EIGRP is cisco proprietary

3>1PV6-RIPng and EIGRP for IPV6 are example of IPV6 routong protocols.

now its time for LS routing protocols and again it is classified on same parameters that is classless,ipv6.but in this classification classfull is not present

1>CLASSLESS-OSPFv2 and IS-IS are example of classless routing protocols of link state

2>IPV6--OSPFv3 and IS-IS for IPV6 are example of IPV6 of link state routing protocols..

now its time for EXTERIOR GATEWAY PROTOCOLS PATH VECTOR,again classification on same parameters classful,classless,ipv6.let me give you example to make it more clear.

1>CLASSFUL-- EGP is an example of classful exterior gateway protocols path vector

2>CLASSLESS--BGPv4 is an example of classless exterior gateway protocols path vector

3>1PV6-BGPv4 FOR IPV6 is an example of ip version 6 exterior gateway protocols path vector

i am providing some images of diffrent protocols which will make you help to understand this stuff-
