Interior Gateway Protocol

IGP stands for Interior Gateway Protocol. This term refers to a type of routing protocol used within a single autonomous system (AS) to facilitate the routing of data packets between routers in that network. IGPs are critical for managing routing information between different networks or domains and help ensure efficient data flow across internal networks.

Examples of common Interior Gateway Protocols include Open Shortest Path First (OSPF) and Routing Information Protocol (RIP), both of which are widely utilized in networking environments to maintain accurate and up-to-date routing tables. Understanding IGP is essential for network security analysts as it plays a key role in the overall performance and security of network infrastructures.
