Open shortest path first
OSPF is a link-state routing protocol.
There are actually two OSPF and IS-IS
Rip ospf
OSPF is short form of open shortest path first. OSPF is based on linked state routing.

BGP is Border Gateway Protocol and OSPF is Open Shortest Path First.
OSPF
OSPF stands for open shortest path first. OSPF is an exterior routing protocol. OSPF uses Path vector routing algorithm.
They are organized in Areas
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.
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.
A routing protocol is a protocol that routers use to tell each other about available routes. Some of the routing protocols include RIP, EIGRP, OSPF, IS-IS, BGP.
