Comparison between eigrp and ospf

Another BGP-specific feature that you can set is dampening. Figure illustrates the time and penalty relationship in route dampening. The limitation of IGRP is that it experiences the routing loop problem.

What is difference between EIGRP & OSPF ?

OSPF is a link state protocol. It gives rise to the hybrid routing which is developed by merging the features of the distance vector routing and link state routing.

DUAL uses bandwidth and delay by default to calculate the composite metric using a complex formula, but we can add Load and reliability as additional parameters. The valid range is from 1 to 20,; the default is Every routing protocol has and classless routing based upon the subnet mask.

A Slight Problem with Distributing EIGRP into MP-BGP

It supports subnet specific, host-specific, and classless routes, also, classful network specific routes. Figure Route Map Practical Example: OSPF also provides maximum throughput and lowest queuing delay.

Active router sends its routing table to the others and listens for their updates. The EIGRP can create summary routes at any point in the network in a short period, instead of depending on the conventional distance vector algorithm where only classful addressing was allowed.

Basic differences between RIP 1, RIP2, IGRP, EIGRP and OSPF and BGP.

The trickiest bit to understand is what to advertise. The link states are transmitted all through the autonomous system to the routers to update the database. It also provides the unequal metric load balancing for spreading the traffic flow effectively along the network.

It is a link state routing protocol and is most commonly grouped with interior gateway protocols. The set tag command enables you to set the administrative tag of route.

What is Administrative distance (AD) | Difference between AD & Metric

OPNET model is divided into three domains [24]. An instable route in your autonomous system will cause constant sending and withdrawing of messages to other autonomous systems. OSPF backbone are known as backbone routers.

The second network topology and in the routing updates and the version of OSPF was released in and published subnet mask together with the network address are in RFC Passive router listens for updates from other participants but does not propagate its own routing entries.

It is a distance-vector routing protocol in advance within the optimization to lessen both the routing unsteadiness incurred after topology alteration, plus the use of bandwidth and processing power in the router which support enhanced interior gateway routing protocol will automatically reallocate route information to IGRP Enhanced Interior Gateway Routing Protocol neighbors by exchanging the 32 bit EIGRP Enhanced Interior Gateway Routing Protocol metric to the 24 bit IGRP metric.

Note an important difference in how the prepend command works with inbound and outbound route maps. Router used it to exchange routing data within an independent system. Sample code is provided only to illustrate how to enable VRF routing. Split horizons and route poisoning is the solution to the routing loop problem.

For IGPs, the tag value is usually set with a route map and the set tag command. The third version of OSPF was included. The set community command enables you to form community membership.

Understand the significance of administrative distance and metrics when working with routers

So when a network becomes unreachable from the best path, it does its local computation to figure out the next alternative path.BGP - The Border Gateway Protocol / Advanced Internet Routing. Watch a Video to find out the differences of Cisco IOS four editions LAN Lite, LAN Base, IP Base and IP Services.

One of the most asked questions after completion of Cisco training like CCNA or CCNP Routing and Switching is “Which protocol is better EIGRP or OSPF?” and the answer is the most common answer for any comparison question – “It depends”. I have tried to cover positives and negatives of both and tried to be as unbiased as possible.

Routers in EIGRP knows only what their neighbors forward to them, while OSPF every router know the all topology of the area. in my opinion thats the more important difference in between the two protocols.

EIGRP and OSPF Comparison Select a new route Propagate the changed route informationROUTE SELECTION- Routing protocols compare route metrics to select the bestroute from a group of possible routes. Route metrics are computed by assigning acharacteristic.

comparison 3 protocols (OSPF, RIP, and EIGRP) and the results show that EIGRP has the smallest routing time, memory time and CPU time, and the least delay time but OSPF.
