By default, the preference for the neighbor of NBMA interface is 1.

4.2.9 Setting the Interval of Hello Packet Transmission

Hello packets are a kind of most frequently used packets, which are periodically sent to
the adjacent router for discovering and maintaining the adjacency, and for electing DR
and BDR. The user can set the hello timer.
According to RFC2328, the consistency of hello intervals between network neighbors
should be kept. The hello interval value is in inverse proportion to the route
convergence rate and network load.
Perform the following configuration in Interface view:
Table 4-9 Setting the Interval of Hello Packet Transmission
Set the hello interval of the interface
Restore the default hello of the interface
Set the poll interval on the NBMA interface
Restore the default poll interval
By default, p2p and broadcast interfaces send Hello packets every 10 seconds, and
p2mp and nbma interfaces send the packets every 30 seconds.

4.2.10 Setting a dead timer for the neighboring routers

The dead timer of neighboring routers refers to the interval in which a router will regard
the neighboring router as dead if no Hello packet is received from it. The user can set a
dead timer for the neighboring routers.
