Thank you Andrija,
Indeed tested that, if ON "bypass vlan overlap" option, it is possible
to create 2 shared networks in the same vlan.
IP gets assigned but for some reason the interface is shutdown in some
time(Ubuntu 20). I am now troubleshooting the reason for this.
The design I am trying to create current is - 3 groups of users - lets
call them QA and DEV and ADMIN teams.
- Network A is for QAs.
- Network B is for DEVs.
- ADMIN should have access to both networks.
I tried that setup with one parent domain (admins) and to child (QA and DEV).
Assigning a network to child domain DEV hides the network from QA. ADMIN domain
see the network but cannot create instances inside.
If those 3 accounts are under one domain is it possible to:
- assign Network A to be operated and visible only to QA and Admins
- assign Network B to be operated and visible only to DEV and Admins
The only solution I have found so far is the following:
- Define 2 networks - A and B with VR (DHCP, DNS, USERDATA) only available to
ADMINS so nobody sees them
- Define L2 network AA with USERDATA assigned to QA that overlaps vlan id A
- Define L2 network BB with USERDATA assigned to DEV that overlaps vlan id B
Both users and admins can create instances. Users will not be able to change or
choose IP address.
Regards,
Jordan

Considering you are trying to create 2 shared networks (irrelevant of their IP
range), and I ASSUME you want them on the same VLAN? - then I don't think this
alone is possible (2 network with the same VLAN)
If you can do it, then it's easy to test what you are asking.... and have first
hand-answer :)
IN ACS workdl, in theory, 2 DHCP CAN operate in the same network, since ACS
provisions explicit DHCP reservations for each IP - i.e. you can't just boot
another VM (provisionined manually, outside ACS) in the same VLAN - as DHCP
will reject to give it an IP.
Best,
