AlwaysOn setup - using same Windows Cluster Name

    Hello All,
    I'm in the process of setting up AlwaysOn on a new cluster in one location and planning to replicate to another cluster in a location in another continent.  The network team provided the same Windows Cluster Name (e.g. SQL2014.global.abcd.com) to be used for both SQL clusters in the spec.  

    Will this cause a conflict with AD, DNS, SQL Server, AlwaysOn, etc?  Or will it still work?  My apologies if I  am not asking the question correctly since this is a first time setup for me.  But I will try to clarify any further info required.

    Thanks

    If it's in the same domain, it won't work, they need to be unique. 
    Instead, stretch your Windows cluster over the 2 regions, so all nodes belong to the same Windows Cluster, providing geo-failover.

    Cluster roles use a Client Access Point, in this all network names need to be unique, as do the IP addresses for each network name
