Which statement is correct about interior gateway protocols (IGPs) vs. exterior gateway protocols (EGPs)?
Answer Options
IGPs are used to exchange information between autonomous systems.
EGPs are used to exchange information between routers within an autonomous system.
IGPs are used to exchange information between routers within an autonomous system.
EGPs are used in the core of an internal network.
Correct Answer: C
Explanation
Interior routing protocols are used internally inside of a network. The functional difference is that IGPs exchange information within an autonomous system, and EGPs exchange information between autonomous systems. Interior routing protocols are used to exchange information between routers within the same autonomous system. Exterior routing protocols can be used to exchange routing information between autonomous systems. Exterior routing protocols are used on the edge of a network, usually facing the Internet.
