How does the EIGRP metric calculation differ from other routing protocols such as OSPF or BGP?

The EIGRP metric calculation differs from other routing protocols such as OSPF or BGP primarily in its use of a more complex formula that takes into account multiple factors including bandwidth, delay, load, and reliability. Unlike OSPF which primarily relies on cost-based metrics or BGP which focuses on path attributes and policies, EIGRP uses a composite metric that provides a holistic view of network performance.

Specifically, the EIGRP metric calculation includes the calculation of the feasible distance (FD) and the reported distance (RD), which allows for efficient and optimized route selection based on a combination of quantitative and qualitative factors. This dynamic approach to metric calculation in EIGRP sets it apart from other routing protocols and enables faster convergence and more effective route decision making.
