Classfull routing protocol is a routing protocol that strictly. follows the classfull IP like IGRP,RIP

Classless Routing A scheme which allocates blocks of Internet addresses in a way that allows summarisation into a smaller number of routing table entries.

classful- it wont send subnet mask in its route updateclassless- it will send subnet mask in its route update and support summarization,CIDR,VLSM.RIP1-classfullrip2-classlessMulticasting-sending data only to a set of systems. class d is used for multicastingvlsm-Lan network having different subnetmask

What isVLSM? VLSM: Is nothing but Variable Length Subnet mask.It is the process of subnetting the subnetted addMulticasting: Is nothing but sending the message to particular number of computer in side the LAN or outside the LAN.

Diff bet RIPv1 & RIPv2 ?Both RIPv1 and RIPv2 are based on hop count but RIPv2 supports Variable Lenght Subnet masking (VLSM)

1) Classful & Classless routing

Classful routing : Routing Protocol that do not send subnet mask information when a route update is sent out. All devices in the network must use the same subnet mask

Eg : RIP V1

Classless routing : Routing that sends subnet mask information in the routing updates. Classless routing allows VLSM (Variable Length Subnet Masking)

Eg : RIP V2 , EIGRP , & OSPF.

2) Difference between RIP V1 & RIP V2.

RIP V1 : Distance Vector , Maximum Hop count of 15 , Classful , No Support for VLSM , No support for Discontigious networks.

RIP V2 : Distance Vector , Maximum Hop count of 15 , Classless , Supports VLSM networks , Supports Discontigious networks

3) Mulitcasting : Any Communication between a single sender and multiple receivers.

In Networking Multicast messages are sent to a defined subset of the network addresses.
