For this example, you could conceivably create three new core groups, create a cluster of 40 members in each of these core groups, and deploy the application in these three clusters.
For this dynamic routing to work properly, the core groups containing the ODRs and the core groups containing the target cluster members must be bridged together using CGBS.
In the core, the black holes experience a range of interactions, sometimes forming binary pairs and sometimes being ejected from the cluster completely.
