[FROG] OpenFabric - not allowing >2 nodes per link?

Good day, I've been testing OpenFabric for mesh type setup, but also have some redundant links that have more than 2 nodes on the same VLAN/ethernet bridge/switch. Those multiple nodes per link seems to not have a consistent route view, and as such I need to get some more "noob"/how-to documentation to understand if that is part of the design criteria, or a FRR 8.5 to 9.0 "feature"?
