Correct answer & explanation
Successor: Next-hop router for the best route to a destination
In EIGRP, successors are the next-hop routers for the best path to a destination. Feasible successors serve as backup next-hop routers that meet the feasibility condition. Neighbors are directly connected EIGRP routers that exchange Hello packets. Feasible Distance is the lowest metric from the local router to a destination. Reported Distance is the metric that a neighbor advertises for a specific route.
Quick reference
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
