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 configu...read more
