What is an internal routing protocol?

An interior gateway protocol (IGP) is a type of routing protocol used for exchanging routing table information between gateways (commonly routers) within an autonomous system (for example, a system of corporate local area networks). This routing information can then be used to route network-layer protocols like IP.

What does interior gateway protocol do?

An interior gateway protocol (IGP) is a dynamic route update protocol used between routers that run on TCP/IP hosts within a single autonomous system. The routers use this protocol to exchange information about IP routes. For example, one route can represent addresses from 9.1. 1.0 through 9.1.

Which interior routing protocol do Cisco routers prefer?

It shows that the RIP routes are preferred. They are learned with an administrative distance of 90, although the default is 120. Note that the new administrative distance value is relevant only to the routing process of a single router (in this case R1). R2 still has IGRP routes in its routing table.

What is interinterior gateway routing protocol?

Interior Gateway Routing Protocol (IGRP) is a proprietary distance vector routing protocol used to communicate routing information within a host network. It was invented by Cisco.

What is an interior protocol?

An interior protocol is a routing protocol used inside – interior to – an independent network system. In TCP/IP terminology, these independent network systems are called autonomous systems. [9] Within an autonomous system (AS), routing information is exchanged using an interior protocol chosen by the autonomous system’s administration.

What are the different types of routing protocols?

Routing protocols are divided into two general groups: interior and exterior protocols. An interior protocol is a routing protocol used inside – interior to – an independent network system. In TCP/IP terminology, these independent network systems are called autonomous systems.

What are interior gateway protocols (IGPs)?

Interior Gateway Protocols (IGPs) handle routing within an Autonomous System (one routing domain). In plain English, IGP’s figure out how to get from place to place between the routers you own.
