BGP and OSPF are routing protocols used in computer networks. BGP (Border Gateway Protocol) is used to exchange routing information between different autonomous systems (AS). OSPF (Open Shortest Path First) is used to find the shortest path between routers within the same autonomous system (AS). BGP is a path-vector protocol while OSPF is a link-state protocol. BGP is used in large-scale networks while OSPF is used in smaller networks. BGP is more complex and requires more configuration than OSPF. BGP is used by Internet Service Providers (ISPs) to connect to each other while OSPF is used by companies to connect their internal networks. BGP uses TCP port 179 while OSPF uses IP protocol 89.
