Open Shortest Path First (OSPF) is a routing protocol used in internet Protocol (IP) networks to determine the most efficient path for data to travel across a network. It operates as a link-state routing protocol, enabling routers to share information about the network's topology and calculate the shortest path using Dijkstra's algorithm. OSPF is designed for scalability and can support large and complex networks, allowing for fast convergence and efficient routing updates. Additionally, it supports hierarchical network design through the use of areas, which helps optimize routing efficiency and manage large networks effectively.

Is OSPF a classful or classless link-state routing protocol?

OSPF is a classless link-state routing protocol. RIP version 1 and IGRP are both classful distance vector routing protocols, EIGRP is a hybrid protocol that supports classless addressing.


What is OSPF adjacencies?

OSPF is a link-state routing protocol that helps Routers exchange IP routes. OSPF Adjacencies is the established "neighborship" between two OSPF routers in order to make the exchange of routes. In this case, Adjacency means the same as "peering", that the OSPF speakers (routers) are able to "talk" to each other.
