Do routers dynamically discover neighbors on OSPF Broadcast networks?

In OSPF (Open Shortest Path First) on broadcast networks, routers do indeed dynamically discover their neighbors. This process occurs through the exchange of Hello packets. When OSPF is configured on a router in a broadcast network, such as Ethernet, the router sends out Hello packets to the local subnet. These packets are sent to a multicast address (224.0.0.5), which means all OSPF routers on that network will receive them.

Upon receiving these Hello packets, routers identify each other and form neighbor relationships. The Hello protocol helps establish certain parameters, such as the Hello and Dead intervals, which are necessary for maintaining the neighbor relationship. The discovery of neighbors is a fundamental aspect of how OSPF operates to build a complete topology of the network, allowing routers to efficiently manage routing information and ensure a robust routing environment.

This dynamic discovery process is not limited to just the initial configuration; it continues as routers maintain their neighbor relationships. Therefore, the correct answer is that routers dynamically discover neighbors on OSPF broadcast networks.
