Description: The process of ‘gaining’ in the context of EIGRP (Enhanced Interior Gateway Routing Protocol) refers to the ability to acquire more bandwidth or network resources to optimize communication between devices in a network. EIGRP is an advanced routing protocol developed by Cisco that allows routers to exchange information about the network topology efficiently. Gaining in this context means that a router can dynamically adjust its routes and resources to maximize network performance, ensuring that data flows as effectively as possible. This process is based on metrics such as bandwidth, latency, load, and reliability, allowing EIGRP to select the best available routes. The ability to gain bandwidth is crucial in environments where data demand is high, as it enables organizations to maintain optimal performance and a smooth user experience. Additionally, the use of EIGRP facilitates rapid network convergence, meaning that changes in topology are reflected almost instantaneously, allowing routers to adapt their routes and resources efficiently. In summary, gaining in EIGRP is a fundamental aspect of effective network management, ensuring that resources are used optimally and that communication between devices is fast and reliable.
History: EIGRP was introduced by Cisco in 1993 as an advanced routing protocol that combines features of distance vector and link state protocols. Its development was based on the IGRP (Interior Gateway Routing Protocol), which was created by Cisco in 1986. EIGRP was designed to overcome the limitations of IGRP, offering faster convergence and better bandwidth utilization. In 2013, EIGRP was published as an open standard by the IETF, allowing for broader adoption across various networking platforms.
Uses: EIGRP is primarily used in enterprise networks to facilitate efficient data routing between multiple routers. Its ability to adapt to changes in network topology and its rapid convergence make it ideal for environments where availability and performance are critical. Additionally, EIGRP allows for the implementation of advanced routing policies, enabling network administrators to optimize traffic according to the specific needs of the organization.
Examples: A practical example of EIGRP in action is a company that uses multiple branches connected through a WAN. By implementing EIGRP, the company can ensure that traffic between its offices is routed efficiently, even if there are changes in the network, such as the addition of new branches or modification of existing links. This allows for smooth communication and optimal use of available bandwidth.
