CIDR ranges for Red Hat OpenShift Service on AWS (ROSA) cluster

Hi team,

I want to create a Red Hat OpenShift Service on AWS (ROSA) cluster

and I'm not sure if I should give

• Machine CIDR:
• Pod CIDR:

the same IP CIDR range which is the subnet CIDR, since machines and pods are running inside the same VPC, inside the same subnets.

or those values should be different?

my understanding is that machines and pods are running inside the same subnet so

• Machine CIDR:
• Pod CIDR:

logically have the same IP range which is the IP range of the subnet in which they are running.

for service CIDR can use always this value?

• Service CIDR: 172.30.0.0/16

is there a specific workshop that walkthrough detailed steps on how to create a ROSA cluster inside private VPC with a private link

thank you!
