Which metric does EIGRP use for route selection?

• A. Bandwidth alone
• B. A composite metric based on multiple factors
• C. Distance from source to destination
• D. Hop count only

Answer: (B)

EIGRP, or Enhanced Interior Gateway Routing Protocol, uses a composite metric for route selection that is based on multiple factors. This composite metric incorporates various elements, including bandwidth, delay, load, reliability, and even MTU (Maximum Transmission Unit) size. By considering these different aspects, EIGRP can make informed decisions about which path offers the best performance for data transmission, thus ensuring efficient routing within a network. The use of a composite metric enables EIGRP to provide a more accurate assessment of network conditions compared to simpler routing protocols that rely solely on a single metric, such as hop count or bandwidth alone. This multifaceted approach allows EIGRP to select the most advantageous routes, taking into account overall network performance rather than just a singular measurement.
