Is Igrp An Exterior Gateway Protocol?


Router protocols include: Interior Gateway Protocol (IGRP) Open Shortest Path First (OSPF) Exterior Gateway Protocol (EGP) Enhanced Interior Gateway Routing Protocol (EIGRP)


IGRP protocol is an interior gateway routing protocol which is used within a group of linked networks an either managed by a single entity or group of entities. To connect these set of networks the external gateway protocol is used. IGRP is a successor of RIP (Routing Information Protocol) which contains more features than the RIP.

Frequently Asked Questions

What is Igrp Internet gateway routing protocol?

Interior Gateway Routing Protocol (IGRP) is a distance vector interior gateway protocol (IGP) developed by Cisco. It is used by routers to exchange routing data within an autonomous system. IGRP is a proprietary protocol. ... This contrasts with classless routing protocols that can use variable length subnet masks.

Is OSPF an Exterior Gateway Protocol?

These dynamic routing protocols are commonly broken into two major categories: Interior routing protocols or IGP (Interior Gateway Protocols) and Exterior routing protocols or EGP (Exterior Gateway Protocols). ... RIP and OSPF are examples of IGP, while BGP and IS-IS can be used as either an IGP or EGP.

What does the interior gateway routing protocol ( IGRP ) mean?

What does Interior Gateway Routing Protocol (IGRP) mean? 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.

Is there an alternative to IGRP for gateways?

Each gateway only needs to solve part of the problem, and it only has to receive a portion of the total data. The major alternative to IGRP is Enhanced IGRP (EIGRP) and a class of algorithms referred to as SPF (shortest- path first).

Which is the current implementation of IGRP-Cisco?

The current implementation of IGRP handles routing for TCP/IP. However, the basic design is intended to be able to handle a variety of protocols. No one tool is going to solve all routing problems. Conventionally the routing problem is broken into several pieces.
