| Basis of Comparison | RIP | IGRP |
|---|---|---|
| Full form | RIP stands for routing information protocol. | IGRP stands for interior gateway routing protocol. |
| Description | RIP is a distance vector-based routing protocol. | IGRP is a distance vector based interior gateway routing protocol. |
| Determination of route | RIP depends on the number of hops to determine the best route to the network. | IGRP considers many factors before decides the best route to take, i.e., bandwidth, reliability, MTU and hops count. |
| Standard | RIP is a industry standard dynamic protocol. | IGRP is a Cisco standard dynamic protocol. |
| Organization used | RIP is mainly used for smaller sized organizations. | IGRP is mainly used for medium to large-sized organizations. |
| Maximum routers | It supports maximum 15 routers. | It supports a maximum 255 routers. |
| Symbol used | RIP is denoted by 'R' in the routing table. | IGRP is denoted by 'I' in the routing table. |
| Administrative distance | The administrative distance of RIP is 120. | The administrative distance of IGRP is 100. |
| Algorithm | RIP works on Bellman ford Algorithm. | IGRP works on Bellman ford Algorithm. |
