OSPF, BGP, and EIGRP are routing protocols used in networking to determine the best path for data packets to travel.

• OSPF (Open Shortest Path First) is a link-state routing protocol that uses Dijkstra's algorithm to calculate the shortest path to a destination.

• BGP (Border Gateway Protocol) is a path vector routing protocol used to exchange routing information between different autonomous systems on the internet.

• EIGRP (E...read more
