Q: What are the disadvantages of RIP?
A: The main disadvantages of RIP are:
- Slow Convergence: When a network topology changes, it takes a long time for RIP to converge and update all routing tables. This is due to its periodic update cycle and the distance-vector algorithm.
- Not Scalable: RIP is only suitable for small to medium-sized networks. As the network grows, the routing information overhead increases significantly, consuming bandwidth and processing power.
- No VLSM Support: RIP cannot support Variable Length Subnet Masks (VLSM), which limits its flexibility in complex network designs and can lead to inefficient IP address usage.
- Poor Security: RIP does not authenticate its routing updates, making it vulnerable to attacks like route poisoning and spoofing, which can lead to network outages or data interception.
