Routing Information Protocol

Limitations

While utilizing RIP, users may run into various limitations. For example, the Routing Information Protocol results in increased network traffic due to the checks and updates it performs on neighboring routers every 30 seconds. Furthermore, since RIP only updates neighboring routers, updates for non-neighboring routers can be forgotten since the information is not immediately accessible.

Another limitation of RIP is the enforcement of a maximum hop count of 15. As a result, remote routers in large networks may not be able to be accessed or reached. Furthermore, the closest path may not be the shortest path. This is because RIP does not take various factors into consideration when calculating the shortest path.
Example RIP pratacol in cisco pacet tracer.
