Hi,

This is route print output:

As you see, 1.1.1.1/24 is added in routing table.
I want to delete a subnet (like /32 or bigger) from this but I get error:

route delete -p 1.1.1.10/32 192.168.1.1
route delete -p 1.1.1.0/25 192.168.1.1

Error:

The route deletion failed: Element not found.

I know I can remove the whole /24 subnet and then use a Python script to generate the desired subnets, but my question is whether it's possible to remove a smaller subnet in routing table.
Windows 10, PowerShell version is 5.1 (18200).

No, you can't delete a route that doesn't exist.
