Objetivos descrever o contexto e a histria do enhanced interior gateway routing protocol eigrp. Red font color or gray highlights indicate text that appears in the answer copy only. Eigrp is an enhanced version of the igrp developed by cisco. This paper should be used as an informationonly document intended as a technology introduction and does not represent a protocol specification or product description. Eigrp adheres to the following hybrid characteristics. Eigrp was designed by cisco system as a proprietary. This paper is an introduction to the interior gateway routing protocol igrp suite of routing protocols designed and developed by cisco systems.
Eigrp general hybrid rputing protocol uses dual algorithm protocol independant classless routing protocol support equal unequal path load balancing eigrp tables neighbor table topology table routing table eigrp routing table terms active state router is trying to find a route. A routing domain representing a physical nonvirtual view of the network topology consisting of attached. Eigrp uses the same distance vector algorithm and distance information as igrp. Eigrp concepts this section describes some details about cisco s eigrp implementation. Eigrp is a successor to the interior gateway routing protocol igrp.
Eigrp uses diffusing update algorithm dual to determine the best path among all feasible paths. Protocol igrp disenado y desarrollado por cisco systems. Both are owned by cisco and operate only on their devices. Eigrp asks dual to make routing decisions and the results of which are stored in the ip routing table. Eigrp is responsible for redistributing routes learned by other ip routing protocols. Eigrp, instead of counting on full periodic updates to reconverge, builds a topology table from each of its neighbors advertisements. I want to clear up something that has somewhat bothered me for a while now. Eigrp is an advanced distance vector routing protocol. In this tutorial well learn and configure about the eigrp in cisco packet tracer. Eigrp enhanced interior gateway routing protocol eigrp is a ciscoproprietary hybrid routing protocol, incorporating features of both distancevector and linkstate routing protocols. Enhanced interior gateway routing protocol eigrp is an advanced distance vector routing protocol based on the principles of the interior gateway routing protocol igrp.
