Interior Gateway protocol atau IGP dan Eksterior Gateway Protocol atau EGP

IGP

An autonomous system (AS), otherwise known as a routing domain is a collection of routers under the same administration. A typical example is the company's internal network and the Internet service provider, because the Internet is based on the concept of an autonomous system, two types of routing protocols needed interior and exterior routing protocol

IGP is used for routing between autonomous systems routing between autonomous systems

EGP is used for routing between autonomous systems routing between autonomous systems.

Characteristics of IGP and EGP Routing protocol

IGP is used for routing within a single domain routing networks that are within the control of a single organization

EGP on the other hand is designed for use between different autonomous systems which are under different administrative control.

Specific examples of IGP protocols include Open Shortest Path First (OSPF), Routing Information Protocol (RIP) and Intermediate System to Intermediate System (IS-IS).

Conversely, the exterior gateway protocol used to exchange routing information between autonomous systems and rely on doctors to complete the route within the autonomous system.
