What are the default K-values for EIGRP?

The default K-values for Enhanced Interior Gateway Routing Protocol (EIGRP) are specifically set to K1 = 1, K2 = 0, K3 = 1, K4 = 0, and K5 = 0. These values are used to calculate the EIGRP metric, which influences route selection and helps determine the best path through the network.

Here’s a breakdown of the K-values:

• K1 monitors bandwidth, so setting this value to 1 means bandwidth plays a role in metric calculation.

• K2 measures load but with a default of 0, it means load does not factor into the metric.

• K3 represents delay, and having this set to 1 means delay impacts the metric.

• K4 and K5 are defaults set to 0, indicating that reliability and MTU (Maximum Transmission Unit) do not contribute to the default route metric in EIGRP.

This configuration helps focus the routing decisions primarily on bandwidth and delay while minimizing the effects of load, reliability, and MTU in most standard scenarios. These defaults can be adjusted if specific network requirements demand consideration of load or reliability, but for general operation, using these default values simplifies configuration and promotes efficient routing.
