What is OSPF ? Why we use OSPF ? Ad Value?

Question

Accepted Answer

OSPF (Open Shortest Path First) is a routing protocol used to determine the best path for data packets in a network.

OSPF is used to efficiently route traffic in large networks by calculating the shortest path between routers.
It is a link-state routing protocol that uses Dijkstra's algorithm to determine the best path.
OSPF is preferred over other routing protocols like RIP due to its faster convergence time and scalability.
It supports VLSM (Variable Length Subnet Masking) and CIDR (Classless Inter-Domain Routing) for efficient IP address allocation.
OSPF provides better load balancing and redundancy in network paths.
Example: In a large enterprise network with multiple routers and subnets, OSPF can dynamically adjust routing paths based on network changes.
