EIGRP Metric Calculation
EIGRP (Enhanced Interior Gateway Routing Protocol) metric calculation is crucial for efficient network routing. It helps determine the best path for data transmission based on bandwidth, delay, load, and reliability.
How to Use This Calculator
- Select the bandwidth and delay values.
- Enter the MTU (Maximum Transmission Unit) value.
- Click ‘Calculate’.
Formula & Methodology
The EIGRP metric is calculated as follows:
Metric = (K1 * Bandwidth + K2 * Delay + K3 * Load + K4 * Reliability) / 256
Where:
- K1, K2, K3, and K4 are constants (default values: 1, 1, 1, 1).
- Bandwidth is the minimum bandwidth of the link in Kbps.
- Delay is the total delay of the link in microseconds.
- Load is the average queue length of the link.
- Reliability is the sum of the reliability values of the links.

Data & Statistics
| Bandwidth (Kbps) | Delay (usec) | MTU | Metric |
|---|---|---|---|
| 1000 | 1000 | 1500 | 2000 |
| 2000 | 2000 | 1500 | 1500 |
Expert Tips
- Adjust K1, K2, K3, and K4 values to prioritize specific metrics.
- Regularly update EIGRP metrics to adapt to changing network conditions.
