I have a project assignment that consists of 3 routers, the ISP, and 2 company routers, the ISP can address a network /24 IPv4.
I delegated a /25 to DNS servers and a /26 to one company and 2*/30 to the second company and the other goes to the VPCS that represents the "internet".
On the company server, I was trying to subnet the /26 into 3 networks for each department but looks like I'm doing something wrong.
F1/1 is connected to the ISP with an IPv4 of 184.108.40.206/26
I thought that I could set the other interfaces as
But I was wrong, if try, it tells me that there's an overlapping error.
Im not sure what I'm doing wrong here, any help would be appreciated
