Hey Ruslanas, You are be able to customize the networks to all use the same CIDR and set different IP allocation pools from within the it. Have a look at this Create Network Environment File <https://tripleo-docs.readthedocs.io/en/latest/advanced_deployment/network_isolation.html#create-network-environment-file> for reference of the parameters you want to change. That has the disadvantage of allocating many IPs from the same subnet when, in theory, you should technically be able to use one. I am not sure if/how that is possible in TripleO. The ask we hear from most of our operators is usually to allow more separation of networks (not less). I hope this helps point you in the right direction!

Hi all,
I am doing some testing and will do some deployment on some remote hosts.
Remote hosts will use provider network only specific for each compute.
I was thinking, do I really need all the External, InternalAPI, Storage, StorageManagemnt, Tenant networks provided to all of the nodes? Maybe I could use a Provision network for all of that, and make swift/glance copy on all computes to provide local images.
I understand, if I do not have tenant network, all VM's in same project but in different sites, will not see each other, but it is ok at the moment.
Thank you for your help
