Which routing protocol is regarded as the successor to RIP?

• A. OSPF
• B. EIGRP
• C. BGP
• D. IS-IS

Answer: (B)

The chosen answer, EIGRP, stands out as the successor to RIP due to its advanced features and improvements in routing efficiency. While RIP, or Routing Information Protocol, is a distance-vector routing protocol that uses hop count as its metric, EIGRP, or Enhanced Interior Gateway Routing Protocol, was developed by Cisco to address some of RIP's limitations. EIGRP combines the best characteristics of distance-vector and link-state protocols. It enhances routing decisions by using an advanced metric that takes into account bandwidth, delay, load, and reliability. Moreover, EIGRP supports faster convergence times and allows for better scalability in larger networks, making it a more suitable choice for complex and growing environments than RIP. This capability is particularly important in modern networks where the demand for quicker route recalculation and more efficient data routing has increased. In contrast, OSPF, BGP, and IS-IS have their own specific use cases and scenarios, typically in larger or different types of networks, but they are not directly seen as successors to RIP in the same way that EIGRP is. OSPF and IS-IS are link-state protocols, while BGP is an exterior gateway protocol primarily used for routing between different autonomous systems on the internet.
