Eigrp is a lot easer to implement than ospf if you have an all, mostly cisco environment it is probably the way to go now if you have a mixed environment of several different brands of routers ospf, or bgp make better sense since they are open protocols. When doing a comparison for the metrics between ospf and eigrp ospf takes the lowest bandwidth path to the destination determined by actual bandwidth on a link/ 100mbps (100,000,000 bps. The two versions of ospf naturally have much in common, however there are several important differences in the way the two protocols operate this article seeks to highlight some of the more noteworthy deviations. In ospf two routers are neighbors when they are in touch by means of the hello protocol to be able to be in touch the two routers must have an interface to a common network (eg they're both on the same ethernet segment, or they have a point-to-point link) and some things must be configured identically on those interfaces.
Introduction this document explains two common problems with redistributing routes between rip and ospf or igrp and eigrp rip and igrp will not advertise routes out an interface if those routes are on the same major network, but have a different mask than that particular interface. Lab 114: route redistribution between ospf and eigrp2 (1) vote we will use the following topology to demonstrate how to perform redistribution between eigrp and ospf we assume that all the devices have already configured with the appropriate ip addresses. One major difference between the protocols relates to how they operate in the osi model is-is is a native layer 3 (network layer) protocol, so it is capable of passing routing information for any routable protocol, and it is not restricted to ip like ospf and many other routing protocols are.
Eigrp vs ospf eigrp and ospf are routing protocols used to advertise about routes in a network eigrp is a cisco proprietary protocol, and ospf is an open standard industry protocol, which can also be used with non-cisco devices like juniper. After the implementation, the comparison is made by using different researches and simulations of ospf routing protocol between routing protocols finally, it is concluded that choice of routing protocol depends on different critical. One might assume ospf, with its areas, are the key, but the same lack of planning for eigrp can pelage ospf in the same way setting up areas with lots of routers, or leaking excessive information across abrs, impacts the database size, and computational workload. Basic differences between rip 1, rip2, igrp, eigrp and ospf and bgp. This video explains aspects about ospf and eigrp routing protocols this video will help you compare both the protocols to know more about us.
Ospf makes a lot of sense when that shortest path is really worth pursuing, typically but not always in larger networks, and eigrp seems to be effective for shops with cisco and a need for simplicity and support. Eigrp strengths, weakness, operational requirements and commercial implementation eigrp stands for enhances interior gateway routing protocol eigrp is an enhanced distance vector protocol, relying on the diffused update algorithm (dual) to calculate the shortest path to a destination within a network. The difference between the three is numerous, but without going into detail, basically the metrics that each protocol uses for determining the best routes for each subnet and ultimately learning new routes/subnets is the probably one of the biggest differences.
Rip v1 rip v2 igrp eigrp ospf is-is bgp interior/exterior interior interior interior interior interior interior exterior type distance vector distance vector distance vector hybrid link-state link-state path vector. Eigrp stands for enhanced interior gateway routing protocol it uses dual ( diffuse update algorithm ) for reliability and choosing backup paths it is a hybrid protocol which is also known as advance distance vector protocol ( combination of distance vector & link state protocols . The main alternative to eigrp for most campus lan routing deployments is the open shortest path first (ospf) dynamic routing protocol unlike eigrp, ospf was always an open standard protocol and is an available option on virtually any modern enterprise network hardware made in the past two decades.
Difference between rip and ospf october 4, 2017 1 comment a routing protocol describes the rules that must be followed by a router while it interacts with neighboring routers to learn the path and to maintain the network in the routing tables. 1 ospf is an open protocol whereas eigrp is a cisco propriety protocol 2 ospf is merely a link state protocol whereas eigrp shows characteristics of both link state and distance vector protocol 3 ospf calculates the metric using cost but eigrp uses bandwidth, load, delay and reliability to. Looking at choosing between ospf and eigrp, there are various charecteristics one of which is the simplicity to design out of these 2 protocols, which would be the easier to design and why.
