Why is eigrp better than ospf

Thanks, its fitting. I heard a similar one before but couldn't remember what it was exactly. Thats all i could come up with. One thing more to mention is that EIGRP supports Unequal cost path multipath, meaning that if an EIGRP router has multiple routes to a destination even with unequal costs you can load balance via them. Moreover, a topology change anywhere in the network would cause a convergence event throughout the area.

Totally agree with Ri0N. It depends which one is more suitable for a particular network design. If you encounter a technical issue on the site, please open a support case.

Here, the triggered updates signify that the router will not send updates until and unless something has changed. Further, the incremental updates mean that the router will not send all the information about the network rather just the information that has changed will be shared. On the other hand, OSPF is a link-state routing protocol which resembles a map where the complete information about all the routes within that area is maintained.

Whenever there is any change in the area, all routers in that particular area are needed to recalculate their database and routes. If the best path goes wrong it can fall directly to the alternate best path. In contrast, OSPF follows a different approach due to which it has a greater convergence time.

Conversely, OSPF is an open standard and simple protocol through which the network can be scaled easily. What are their differences on earth? It uses incremental and triggered updates that improve the operational ability and fast converging rate. It can determine the shortest path distance vector and uses metrics like bandwidth, load, and delays to calculate the shortest optimal network route. EIGRP is a complex protocol but can be configured and runs easily in small and large networks. EIGRP protocol is used for passing the information from one to neighboring routers in the same area.

OSPF, a link-state routing protocol, collects link state information from routers in the network and determines the routing table information to forward packets.

If the best path fails, it will automatically switch to the other best way. Whereas, OSPF takes a different technique, which results in a longer convergence time. OSPF, on the other hand, is an open standard and simple protocol that allows the network to scale efficiently.

As OSPF is widely utilized in traditional systems, it provides better support for service providers and data centers. It also improves the sharing of routing information. The primary distinction between both protocols is because EIGRP only exchanges entire routing information once, when neighboring routes are formed, and then it merely tracks modifications.
