Description: The overhead calculation in EIGRP (Enhanced Interior Gateway Routing Protocol) is a method used to determine the amount of resources required for routing within a network. This calculation is fundamental for optimizing network performance, as it allows routers to evaluate the efficiency of available routes and select the most suitable one. EIGRP uses an advanced distance vector algorithm that considers multiple metrics, such as bandwidth, latency, load, and reliability, to calculate the overhead. Overhead refers to the amount of additional traffic that can affect network performance, and its calculation is essential to avoid congestion and ensure smooth communication between devices. By evaluating overhead, EIGRP can dynamically adapt to changes in network topology, making it a highly efficient and reliable routing protocol. This approach enables network administrators to make informed decisions about the configuration and maintenance of the network infrastructure, thus ensuring optimal operation and a better experience for end users.
