Description: The Key Routing Protocol (EIGRP, for its acronym in English) is an advanced routing protocol developed by Cisco that combines features of link-state and distance-vector routing protocols. Its main function is to facilitate the effective transmission of data in networks, optimizing route selection and improving traffic efficiency. EIGRP uses a routing algorithm called DUAL (Diffusing Update Algorithm), which allows routers to calculate the most optimal routes and perform quick updates in case of changes in the network topology. This protocol is known for its ability to handle large and complex networks, offering fast convergence and efficient bandwidth utilization. Additionally, EIGRP supports multiple network protocols, making it versatile and adaptable to various network configurations. Its design allows for the implementation of advanced routing policies, providing network administrators with granular control over traffic and resource management. In summary, EIGRP is an essential component in modern network infrastructure, ensuring smooth and efficient communication between devices.
History: EIGRP was introduced by Cisco in 1994 as a proprietary protocol, designed to overcome the limitations of existing routing protocols at that time, such as RIP and OSPF. In 2013, Cisco decided to open the protocol and made it an IETF standard, allowing its use in a wider variety of network environments.
Uses: EIGRP is primarily used in enterprise and service provider networks, where efficient traffic management and fast convergence are required. It is ideal for environments that require high availability and optimal performance, such as data centers and large-scale networks.
Examples: A practical example of EIGRP would be its implementation in a corporate network connecting multiple branches. By using EIGRP, the company can ensure that traffic between branches is routed efficiently, minimizing latency and maximizing the use of available bandwidth.
