Can OSPF operate over non-broadcast networks?

OSPF can definitely operate over non-broadcast networks, and this is primarily achieved by configuring OSPF for point-to-point or point-to-multipoint networks. In cases where a network does not support broadcast traffic, such as point-to-point links (like a leased line between two routers) or point-to-multipoint configurations (which might be seen in frame relay environments), OSPF can still function effectively.

When configured for point-to-point, OSPF treats the link as a single logical connection between two routers, allowing for the successful exchange of OSPF routing updates without the need for broadcast capabilities. In point-to-multipoint configurations, OSPF can send updates to multiple destinations without needing the broadcasts inherent in typical Ethernet environments.

This flexibility in configuration is what allows OSPF to be robust and applicable in various network types, including those that do not support native broadcast communication. By using these configurations, OSPF can still maintain its purpose of efficiently routing traffic in diverse environments.
