In the OSPF Point-to-point network type, do routers dynamically discover neighbors?

• A. Yes
• B. No
• C. Only if configured
• D. Depends on the topology

Answer: (A)

In OSPF (Open Shortest Path First), the point-to-point network type operates under the principle that each router is directly connected to exactly one other router. This unique topology simplifies the OSPF neighbor discovery process. When OSPF is configured on an interface with a point-to-point designation, the routers automatically discover their direct neighbor without needing any manual configuration or additional commands. The OSPF process sends Hello packets on the network, and since there can only be one neighbor in this configuration, each router recognizes its sole neighbor swiftly and establishes an OSPF adjacency. This automatic neighbor discovery is a fundamental aspect of OSPF's efficiency in point-to-point links, which helps to streamline the routing process and reduce administrative overhead. This is distinctly advantageous in scenarios where quick convergence and efficient use of resources are prioritized. Understanding this aspect differentiates point-to-point networks from other OSPF network types (like broadcast or non-broadcast multi-access), where dynamic neighbor discovery could involve more complex processes.
