Must all S series switches on an OSPF NBMA network be fully meshed

Question: Must all devices on an OSPF NBMA network be fully meshed?

Answer: No, devices on an OSPF NBMA network do not need to be fully meshed. For S series switches supporting OSPF, routes between the DR, BDR, and IP addresses of neighbors must be reachable. If the DR is not determined, you can set the priority of a device to 0 and then the device cannot be the DR. To ensure network robustness, you are advised to build a full mesh NBMA network.
