Illustration of the MetroCluster IP and cluster interconnect network

ONTAP clusters typically include a cluster interconnect network for traffic between the nodes in the cluster. In MetroCluster IP configurations, this network is also used for carrying data replication traffic between the MetroCluster sites.

Each node in the MetroCluster IP configuration has specialized LIFs for connection to the back-end IP network:

• Two MetroCluster IP interfaces

• One intercluster LIF
