- EIGRP uses lowest metric of the following:
- Lowest value across path to destination.
- Only Bandwidth and Delay used by default.
- EIGRP Classic Bandwidth is 10^7 * 256/Interface Bandwidth
- K values need to be the same between neighbors.
- Adjacency will not form if they’re different.
‘show ip protocols’ will show the K values…..
And if they’ve been changed it can be seen in running config.
If the metric weights line is removed all K values go back to default and adjacency comes back.
