In the previous version of RDS 2008 R2 the redirection servers were RDSH servers. In server 2012 this has now changed from RDSH to the RDCB servers.
To configure Redirection you need to add the following Registry key to the connection broker.
HKLM\SYSTEM\CurrentControlSet\Control\TerminalServer\ClusterSettings DefaultTsvUrl tsv://VMResource.1.Virtualpool1
Once you configure the RDCB server or Cluster, you would need to use the following to connect to the server. Otherwise the server will redirect you to the configured VDI pool.
