EIGRP vs OSPF in Routing Protocols

Routing protocols instruct the routers about how to communicate with one another, as well as how each of these devices can transmit data. In a nutshell, it aids routers in route planning and job efficiency.

Businesses must choose the appropriate routing protocols for their network. That may be the difference between EIGRP vs OSPF being able to stream or using a dependable teleconference. The efficiency and pace allow you to operate quickly, obtaining the files you need from various locations inside the network or online.In this article i’ve advice about some routing protocols explained.

Since routing protocols should respond to evolving network situations, including the potential to identify which links are offline and what obstructions occur, it’s often critical for a business network to stay available.

ON THIS PAGE: EIGRP vs OSPF in Routing Protocols


Open Shortest Path First (OSPF) and Enhanced Interior Gateway Routing Protocol (EIGRP) are two of the most often contrasted routing protocols today (EIGRP). Both protocols are classified as interior gateway protocols and operate under the same routing area.

What exactly is OSPF (Open Shortest Path First)?

Shortest Path First (SPF) technology is used in Open Shortest Path First, which is widely used in enterprise networks, to find and effectively communicate routing details between routers on a local area network (LAN). OSPF routers are on the same network and would know about all the routers in that region, since they were designed explicitly for TCP/IP environments. Those in the same location would be able to pass on what they’ve heard to neighbouring routers, who are referred to as neighbours.

Using Dijkstra’s algorithm, an OSPF machine would be able to determine the shortest path to a remote destination or router. The shortest path between the source and destination nodes is found using this algorithm.

EIGRP stands for Enhanced Interior Gateway Routing Protocol.

Enhanced Interior Gateway Routing Protocol (EIGRP) is a network protocol developed by Cisco Systems that helps the routers to exchange information more efficiently than previous protocols. The Interior Gateway Routing Protocol, on which EIGRP is built, is entirely interoperable with routers utilising EIGRP. Novell NetWare and AppleTalk networks also use it.

EIGRP routers retain a copy of their adjacent routers’ routing tables. When it’s time to find a path, it looks through these tables for a suitable choice. When it struggles to locate a path, it will be done for them by a neighbouring router before one is found.

The most effective route will be determined by EIGRP using a diffusing update algorithm that is hosted on a finite state machine that will effectively decide which is the least expensive or most productive path from the origin to the destination.

The Disparities EIGRP and OSPF are two different types of routing protocols.

Both the distance vector algorithm and connection state are used by routers in EIGRP networks. According to distance vector algorithms, routers should notify other routers about changes in their topology. A table will be included for each router that lists the distance between destination nodes and the router itself.

This protocol often demands that the router upgrade itself when the distance details of other routers shifts or if a connection to another router is lost. As a result, EIGRP networks have both the best and alternative paths open, thanks to a diffusing upgrade algorithm that computes the shortest route.

In contrast to EIGRP, link state routing does not communicate with any of the routers in the region. Instead, they communicate with another router and learn about the network’s topology. The Dijkstra algorithm is used in OSPF networks to find the shortest path.

What is the difference between EIGRP and OSPF? Choose the shortest path.

Load, reliability, MTU, bandwidth, wait, and hop count are all used by EIGRP networks to choose the best path. This routers can accept latency and bandwidth by design.

EIGRP would be able to examine all of the available routes from the source to the destination and choose the shortest or better one.

OSPF, on the other side, determines the course based on the cost. It will choose the route with the lowest cost as the better choice.

Some Distinctions
There are a few other variations that may affect the decision about which routing protocol to use. The first is the institutional separation, with internal EIGRP being more reliable than OSPF. As a result, OSPF has a lower distance value than EIGRP.

Furthermore, OSPF routing will use considerably more memory and CPU power than EIGRP. However, the most important factor is that OSPF can be difficult to enforce, particularly in larger networks.

Which is Better for Your Business: OSPF or EIGRP?

OSPF is much easier to set up since it just considers the least expensive option. For limited networks, OSPF can be included. However, as the network grows in size, things may get more difficult. If you have a larger platform, you’ll need to make sure you have the necessary IT expertise to keep things running smoothly.

It performs admirably in a wide range of LAN and WAN settings. Or if you’re mixing and matching computers and routers from various manufacturers. OSPF is an open-source protocol that makes it simpler to customise routers.

CISCO, on the other side, states that EIGRP is an open standard, but the RFC 7868 paper they prepared does not have several of the basic protocols. You won’t be able to use another manufacturer’s router in an EIGRP network if you leave these information out.

For companies that use CISCO routers, the Enhanced Interior Gateway Routing Protocol is ideal. It is less complicated and allows for fast convergence. It’s also a lot simpler to set up.

There’s no way to know which routing protocol is better for your network or requires all of the time. It all depends on a variety of variables, including your IT expertise, the level of difficulty you need, and how quickly your company is expanding. Both the EIGRP and the OSPF have advantages and disadvantages. It all depends on your own preferences.

Both OSPF and EIGRP are Dynamic Routing Protocols, as we all know. OSPF is commonly used due to its good uniform protocol and ability to accommodate products from a variety of vendors. EIGRP is manufactured by Cisco, the largest network hardware provider, who hence controls a large portion of the industry.

What are the variations between OSPF and EIGRP, though? Let’s have a look at their ten gaps.

  1. EIGRP is a Cisco-only protocol, while OSPF is a generic protocol.
  2. OSPF is a connection state protocol, while EIGRP is a distance vector protocol.
  3. Automated description features are supported by EIGRP. It has the ability to automatically summarise at the A.B.C network’s boundary, as well as allow manual setup. OSPF, on the other hand, cannot, and the description must be programmed manually.
  4. EIGRP converges quicker than OSPF since it saves optional successors in its topology chart and can bypass direct successors if none are detected.
  5. The multicast address for EIGRP is, and the OSPF addresses are and
  6. EIGRP route metrics are difficult to understand, and OSPF is a Cost category.
  7. Although EIGRP promotes path summarization, it lacks the principle of hierarchical routing and does not distinguish networks in the same way as OSPF does.
  8. EIGRP should not use a complicated Down-Init-Two-Way mechanism to create a neighbour partnership. A router shares an adjacency with a neighbour as long as it sees the neighbor’s hello packet.
  9. In terms of overview features, EIGRP can be deployed on any configuration on any router, while OSPF can only be implemented on ABR and ASBR and does not provide an interface-based path summary.
  10. EIGRP allows for load balancing with unequal route metrics, while OSPF only allows for equivalent metrics.
