Difference between RIP and IGRP
1. Routing Information Protocol (RIP):
RIP, in which distance vector routing protocol is used for data/packet transmission. In the Routing Information Protocol (RIP), the maximum number of Hop is 15, because it prevents routing loops from source to destination. A mechanism like the split horizon, route poisoning, and hold down is used to prevent from incorrect or wrong routing information. Sally Floyd and Van Jacobson  suggest that, without slight randomization of the timer, the timers are synchronized over time. Compared to other routing protocols, RIP (Routing Information Protocol) is poor and limited size i.e., small network. The main advantage of using RIP is it uses the UDP (User Datagram Protocol).
2. Interior Gateway Routing Protocol (IGRP):
IGRP, in which uses distance vector protocol (interior) to exchange data within a system. It supports multiple metrics for each node which includes delay, load, and bandwidth, to compare the 2 routes which are combined into single metrics. The port number for IGRP is 9 which is used for communication and by default every 90 seconds it updates the routing information.
Difference between RIP and IGRP:
|1||RIP stands for Routing Information Protocol.||IGRP stands for Interior Gateway Routing protocol.|
|2||RIP works on the Bellman Ford algorithm.||IGRP also works on Bellman ford Algorithm.|
|3||It is an industry standard dynamic routing protocol.||It is a Cisco standard routing protocol.|
|4||It is used for smaller organizations.||It is basically used for medium to larger size organizations in the network.|
|5||RIP is a distance vector protocol.||IGRP is also a distance vector protocol.|
|6||It allows maximum hop count of upto 15.||It allows maximum hop count upto 255.|
|7||Its administrative distance is 120.||Its administrative distance is 100.|
|8||It is not a more intelligent dynamic routing protocol.||It is a more intelligent routing protocol than RIP.|
|9||It calculates the metric In terms of Hop Count.||It calculates the metric In terms of bandwidth, load, and delay.|
|10||RIP routing protocol creates two tables in the router: Routing Table, and Topology Table.||EIGRP routing protocol creates three tables In the router: Neighbor Table, Topology Table, and Routing Table.|
|11||RIP protocol does not allow you to create an administrative boundary in the network.||It allows you to create an administrative boundary using Autonomous System (AS) No. in the network.|
|12||VLSM (Variable Length Subnet Mask) feature was not supported in RIPv1 but supported by RIPv2.||VLSM (Variable Length Subnet Mask) is not supported by IGRP.|
