OSPF: The Open Shortest Path First (OSPF) protocol is commonly used by network routers to dynamically identify the fastest and shortest available routes for sending packets to their destination. RIP: The Routing Information Protocol (RIP) uses "hop count" to find the shortest path from one netwo...
OSPF is a link-state protocol. A link can be considered as a router interface. The link state is a description of that interface and of the relationship with its neighboring routers. For example, a description of the interface includes the IP address and mask of the interface, the type of...
What type of protocol is Enhanced Interior Gateway Routing Protocol? EIGRP is an enhanced distance vector protocol that evolved from Cisco's IGRP. Although IGRP is now obsolete, a network that still uses routers based on the protocol can interoperate with EIGRP-based routers because the metrics us...
Why Do We Need OSPF? Before the emergence of OSPF, the Routing Information Protocol (RIP) was the most widely used IGP. RIP is a distance-vector routing protocol which is gradually being replaced by OSPF, due to the former's slow convergence, tendency to form routing loops, and poor scala...
4. Open shortest path first (OSPF) protocolOSPF protocols classify as link-state, interior gateway, and classless protocols. They use the shortest path first (SPF) algorithm to ensure the efficient transmission of data. Internally, this type maintains multiple databases with topology tables and info...

OSPF (Open Shortest Path First) is an interior routing protocol used within a single autonomous system, while BGP (Border Gateway Protocol) is an exterior protocol used for routing between different autonomous systems.
