Interior And Exterior Routing Protocols

Interior routing protocols discover paths between networks whereas exterior routing protocols route between autonomous systems.

Interior and exterior routing protocols. An interior protocol is a routing protocol used inside - interior to - an independent network system. These routing protocols are used to route between autonomous systems. An IGP is typically used within a single organization while an EGP is typically used to connect disparate organizations or large Enterprises to the Internet.

Interior gateway protocols can be divided into two categories. Exterior Gateway Protocols EGP. An autonomous system is essentially a grouping of areas.

Interior gateway protocols type 2 distance-vector routing protocols such as Routing Information Protocol RIPv2 IGRP. There is only one Exterior Gateway Protocol EGP exists now and it is Border Gateway Protocol BGP. Specific examples of IGPs include Open Shortest Path First Routing Information Protocol.

Interior routing protocols serve a different purpose than exterior routing protocols. A routing protocol is the criteria a router uses to route traffic among nodes in the network. Exterior gateway protocols are routing protocols used on the.

These routing protocols information routing within the anonymous system. It can be used within ina an autonomous system. Routing Information protocol version 2RIPv2 Enhanced Interior Gateway Routing EIGRP and Open shortest path first OSPF are its examples.

Areas introduce heirarchy into network architectures. Distance Vector Protocols Routing Information Protocol RIP Interior Gateway Routing Protocol IGRP Link State Protocols Open Shortest Path First OSPF Intermediate System to Intermediate System IS-IS EXTERIOR GATEWAY PROTOCOLS. Interior gateways are gateways that belong to the same autonomous system.
