interface depends on the link layer
protocol.

interface
ospf dr-priority priority
Optional
The default DR priority is 1.
Configuring the OSPF Network Type for an Interface as NBMA
After configuring the network type of an interface as NBMA, you need to make some special
configurations.
Because NBMA interfaces cannot find neighbors via broadcasting Hello packets, you need to specify
neighbors and neighbor DR priorities. (A DR priority of 0 means the router does not have the DR
election right; a DR priority greater than 0 means the router has the DR election right).
Follow these steps to configure the OSPF network type for an Interface as NBMA:
