Drag and drop each OSPF network type on the left to its matching DR election behavior on the right.
Drag a concept onto its matching description — or click a concept then click the description.
Elects a DR/BDR; uses multicast Hellos (224.0.0.5 and 224.0.0.6)
Elects a DR/BDR; requires manual neighbor configuration
No DR/BDR election; uses multicast Hellos (224.0.0.5)
No DR/BDR election; treats each neighbor as a point-to-point link
No DR/BDR election; requires manual neighbor configuration
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Broadcast: Elects a DR/BDR; uses multicast Hellos (224.0.0.5 and 224.0.0.6)
Broadcast network type (e.g., Ethernet) elects a DR/BDR. Non-broadcast (NBMA) also elects DR/BDR but requires manual neighbor configuration. Point-to-point does not elect a DR/BDR. Point-to-multipoint does not elect a DR/BDR. Point-to-multipoint non-broadcast does not elect a DR/BDR and requires manual neighbor configuration.

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.
