Hi, I want to configure UCS domain with seperated sub-domain for each location like Microsoft's scenario. For example: we have 5 sites all over the world the root UCS domain is ABC.COM from Head Quater. Each office will have domain like: siteA.ABC.COM, siteB.ABC.COM, etc... with different subnet. All sub UCS system will connect to root UCS system via VPN site-to-site connection. Please show me how to configure with this case. Thank you.
