Unable to create a linked server that points to an availability group listener.

I don't even know if this scenarios is supported or not, I can't find any documentation on it.

I have a couple SQL 2012 servers setup using AlwaysOn Availability Groups.  The listener (SQLAG1) is setup and working as expected with applications.   The 2 machines are in different subnets, so we are using the MultiSubnetFailover=True on the connection strings to ensure that failover works. 

From an SQL 2014 box I want to create a linked server that points at the Listener.   I'm able create the linked server, but it appears like sql server is not using the MultiSubnetFailover=True and it fails to connect.  Here is what I used to create the linked server;

EXEC sp_addlinkedserver 
@server = N'SQLAG1', 
@srvproduct = N'SQL2012', 
@provider = N'SQLNCLI11', 
@datasrc = N'SQLAG1', 
@provstr = N'Provider=SQLNCLI11.1;Data Source=SQLAG1;MultiSubNetFailover=True', 
@catalog = NULL
GO

Do anyone know if this is supported?  if so what it proper way to create the linked server?  

Thanks!!!
