You’re on the right track! Here’s a quick clarification:

Intranet vs. Internet

  • Intranet: A private network, typically within an organization, used to share information and resources internally. It’s “inside the network.”
  • Internet: The global, public network of networks, connecting countless private, public, academic, business, and government networks. It’s “across networks.”

BGP vs. OSPF

  • BGP (Border Gateway Protocol): Designed for the Internet. It’s the protocol that makes the Internet work by enabling routing between autonomous systems (ASes), which are large networks or groups of networks under a single administrative control.
  • OSPF (Open Shortest Path First): Designed for intranets (or within a single autonomous system). It’s an interior gateway protocol (IGP) used to find the best path for packets as they pass through a set of connected networks under a common administration.

Summary:

  • BGP = Internet (between ASes)
  • OSPF = Intranet (within an AS)
