Cisco’s EIGRP uses metrics; Delay, Bandwidth, Reliability and Load. MTU is NOT used in the calculation of the metric, however the MTU is tracked through the path to find the smallest MTU.EIGRP only uses Delay and Bandwidth with Bandwidth taking precedence
- Bandwidth
- Delay
- Reliability
- Load
EIGRP Metric = 256*((K1*Bw) + (K2*Bw)/(256-Load) + (K3*Delay)*(K5/(Reliability + K4)))
The k values are constants. Their default values are: k1 = 1, k2 = 0, k3 = 1, k4 = 0, and k5 = 0. If k5 = 0
