Definition
-
IGP is a category of routing protocols used to exchange routing information through an autonomous system. An autonomous system is a single routing domain, or network, controlled by one individual or organization.
Function
-
Interior gateway protocol uses metrics such as path bandwidth to determine which path to take when directing a packet, or group of digital data, to a destination. Path bandwidth is the speed or rate that digital information is transferred along that path. Interior gateway protocol uses a mathematical and logic-based formula called an algorithm, which utilizes path bandwidth and other metrics to determine the most efficient route to take when forwarding digital information.

Fun Fact
-
Another major type of routing protocol, called exterior gateway protocol, exchanges routing information between networks, as opposed to within one single network.
