Good day Network Lessons Team! I was investigating the formula of calculating short composite metric with the relic components from IGRP: Load, along with the Reliability. A) 256\*((K1_Scaled Bandwidth) + (K2_Scaled Bandwidth)/(256 – Load) + (K3_Scaled Delay)_(K5/(Reliability + K4))) I saw a lot of sources where we can find the same formula A , but there is another one B (the last parameter (K5/(Reliability + K4) is out of parentheses) B) 256 \* [K1_Scaled Bandwidth + K2_Scaled Bandwidth/(256 – Load) + K3\*Scaled Delay] \* K5/(Reliability + K4) They give us different results. I tested it in GNS3 and observe that formula B is right. What have I missed? --- _[View the full topic](https://forum.networklessons.com/t/eigrp-wide-metrics/2114)._
