I've seen in the configuration guide for interclustering IM&P nodes:
With intercluster peering, you can deploy up to 30 IM and Presence Service clusters in the intercluster mesh, irrespective of whether those clusters are centralized or decentralized.
IM&P Cluster can make up to 6 nodes in total (3 Sub-clusters), so the question is, if i have a full cluster of 6 nodes and want to add the intercluster feature to use the extra resources for Persistent chat rooms, would i be able to add another full sized cluster as intercluster ?
or each intercluster would be only a Pub and a Sub (2 Nodes total).
the guide clearly says up to 30 IM&P clusters but it does not clarify if the other clusters can be a full cluster or Single Sub cluster.
