Creating your file...
You can configure intercluster LIFs in custom IPspaces. Doing so allows you to isolate replication traffic in multitenant environments.
When you create a custom IPspace, the system creates a system storage virtual machine (SVM) to serve as a container for the system objects in that IPspace. You can use the new SVM as the container for any intercluster LIFs in the new IPspace. The new SVM has the same name as the custom IPspace.

List the ports in the cluster:
network port showFor complete command syntax, see the man page.
The following example shows the network ports in

Create custom IPspaces on the cluster:
network ipspace create -ipspace ipspaceThe following example creates the custom IPspace
ipspace-IC1:cluster01::> network ipspace create -ipspace ipspace-IC1
-
Determine which ports are available to dedicate to intercluster communication:
network interface show -fields home-port,curr-portFor complete command syntax, see the man page.
The following example shows that ports
e0eande0fhave not been assigned LIFs:cluster01::> network interface show -fields home-port,curr-port vserver lif home-port curr-port ------- -------------------- --------- --------- Cluster cluster01_clus1 e0a e0a Cluster cluster01_clus2 e0b e0b Cluster cluster02_clus1 e0a e0a Cluster cluster02_clus2 e0b e0b cluster01 cluster_mgmt e0c e0c cluster01 cluster01-01_mgmt1 e0c e0c cluster01 cluster01-02_mgmt1 e0c e0c -
Remove the available ports from the default broadcast domain:
network port broadcast-domain remove-ports -broadcast-domain Default -ports portsA port cannot be in more than one broadcast domain at a time. For complete command syntax, see the man page.
The following example removes ports
e0eande0ffrom the default broadcast domain:cluster01::> network port broadcast-domain remove-ports -broadcast-domain Default -ports cluster01-01:e0e,cluster01-01:e0f,cluster01-02:e0e,cluster01-02:e0f
-
Verify that the ports have been removed from the default broadcast domain:
network port showFor complete command syntax, see the man page.

Create a broadcast domain in the custom IPspace:
network port broadcast-domain create -ipspace ipspace -broadcast-domain broadcast_domain -mtu MTU -ports portsThe following example creates the broadcast domain

Create intercluster LIFs on the system SVM and assign them to the broadcast domain:
Option Description In ONTAP 9.6 and later:
network interface create -vserver system_SVM -lif LIF_name -service-policy default-intercluster -home-node node -home-port port -address port_IP -netmask netmaskIn ONTAP 9.5 and earlier:
network interface create -vserver system_SVM -lif LIF_name -role intercluster -home-node node -home-port port -address port_IP -netmask netmaskThe LIF is created in the broadcast domain that the home port is assigned to. The broadcast domain has a default failover group with the same name as the broadcast domain. For complete command syntax, see the man page.
The following example creates intercluster LIFs
