What cluster peer intercluster connectivity is

Cluster peer intercluster connectivity consists of intercluster logical interfaces (LIFs) that are assigned to network ports. The intercluster connection on which replication occurs between two different clusters is defined when the intercluster LIFs are created. Replication between two clusters can occur on the intercluster connection only, regardless of whether the intercluster connectivity is on the same subnet as a data network in the same cluster.

The IP addresses assigned to intercluster LIFs can reside in the same subnet as data LIFs or in a different subnet. When an intercluster LIF is created, it uses routes that belong to the System SVM that the intercluster LIF is in.

System Manager enables you to create an authenticated cluster peer relationship between clusters that are running Data ONTAP 8.3 or later. An authenticated peer relationship uses passphrases to provide secure intercluster communication.
