The disadvantages of RIP include:
- Increased network traffic: RIP checks with its neighboring routers every 30 seconds, which increases network traffic.
- Maximum hop count: RIP has a maximum hop count of 15, which means that on large networks, other remote routers may not be able to be reached.
- Closest may not be shortest: Choosing the closest path by hop count does not necessarily mean that the fastest route was selected. RIP does not consider other factors when calculating best path.
- RIP only updates neighbors so the updates for non-neighboring routers are not first-hand information.
