OSPF Configuration

However, in many cases, this cannot be implemented and you need to use a
command to change the network type forcibly.
Configure the interface type as P2MP if not all the routers are directly accessible on
an NBMA network. Change the interface type to P2P if the router has only one peer on
the NBMA network.
In addition, when configuring a broadcast network or NBMA network, you can also
specify DR priority for each interface to control the DR/BDR selection in the network.
Thus, the router with higher performance and reliability can be selected as a DR or
BDR.
4.5.1 Configuration Prerequisites
Before configuring the network type of an OSPF interface, perform the following
tasks:
z Configuring the network layer address of the interface so that the adjacent node
is reachable at network layer
z Performing basic OSPF configuration
4.5.2 Configuring the Network Type of an OSPF Interface

Optional
By default, the network type of
an interface depends on the
physical interface.
 Note:
z After an interface has been configured with a new network type, the original
network type of the interface is removed automatically.
z Note that, neighboring relationship can be established between two interfaces
configured as broadcast, NBMA, or P2MP only if the interfaces are on the same
network segment.
