IPspace object replication and subnet configuration requirements

IPspace replication​

You must consider the following guidelines while replicating IPspace objects to the partner cluster:

• The IPspace names of the two sites must match.

• IPspace objects must be manually replicated to the partner cluster.

  Any storage virtual machines (SVMs) that are created and assigned to an IPspace before the IPspace is replicated will not be replicated to the partner cluster.

Subnet configuration​

You must consider the following guidelines while configuring subnets in a MetroCluster configuration:

• Both clusters of the MetroCluster configuration must have a subnet in the same IPspace with the same subnet name, subnet, broadcast domain, and gateway.

• The IP ranges of the two clusters must be different.

  In the following example, the IP ranges are different:

  cluster_A::> network subnet show
   
  IPspace: Default
  Subnet                     Broadcast                   Avail/
  Name      Subnet           Domain    Gateway           Total    Ranges
  --------- ---------------- --------- ------------      -------  ---------------
  subnet1   192.168.2.0/24   Default   192.168.2.1       10/10    192.168.2.11-192.168.2.20
  
  cluster_B::> network subnet show
   IPspace: Default
  Subnet                     Broadcast                   Avail/
  Name      Subnet           Domain    Gateway           Total    Ranges
  --------- ---------------- --------- ------------     --------  ---------------
  subnet1   192.168.2.0/24   Default   192.168.2.1       10/10    192.168.2.21-192.168.2.30
  
  

IPv6 configuration​

If IPv6 is configured on one site, IPv6 must be configured on the other site as well.
