EIGRP K Values Configuration

Hello,
I am going to use the below topology as a reference for my question.

I am trying to manipulate EIGRP path by changing the interface delay on ROUTER-1.
By default, this is how everything looks like.


Then I increased the interface delay and now the prefix is showing up as
FD is Infinity in the EIGRP topology table and the prefix is not in the routing table anymore. Additionally, I am not running any other routing protocol and don’t have any static route either. Please shed some light on it.



Thank you so much in advance.

Best Regards,
Azm Uddin
