VLANs as Private Interconnect Networks

Hi Folks,

We will setup cluster 4.4 with VLANs as private interconnect,

We will build 2 cluster (Cluster 1 and Cluster 2), each cluster are 2 node cluster.

Cluster 1 and cluster 2 will share physical NIC interface for the interconnect through LDOM SR-IOV, to separate the traffic of the interconnect between two cluster we will implement vlan interconnect as desribed in Figure 10 ini :

Figure 10 :

In above figure, we have cluster 1 and Cluster 2.

Cluster 1 : vlan 1.1 and vlan 2.1

Cluster 2 : vlan 1.2 and vlan 2.2

my question on above figure Cluster 1:

I still not figure out the subnet assignment for vlan 1.1 and vlan 2.1 how cluster will assign to it? should vlan 1.1 and 2.1 on same subnet or different subnet? because when we change interconnect address we only input network address and subnet mask :
