Table 4-7 Setting the Interface Priority for DR Election
Configure the interface with a priority for
DR election
Restore the default interface priority
By default, the priority of the Interface is 1 in the DR election. The value can be taken
from 0 to 255.
4.2.8 Setting the Peer
For a NBMA network, some special configurations are required. Since an NBMA
interface on the network cannot discover the adjacent router through broadcasting the
Hello packets, you must manually specify an IP address for the adjacent router for the
interface, and whether the adjacent router is eligible for election. This can be done by
configuring the peer ip-address command.
Perform the following configuration in OSPF view.

Remove the configured peer for the
NBMA interface
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.
